Riemenmann

"He wore golden straps across his body to contain the lethal PSI radiation that poured from him -- and when he removed them, entire armies fell."
-- Description of Llewellyn 709, Booklet 001

The Riemenmann (German: literally "Strap-man"; plural: Riemenmanner) is the rarest and most extreme manifestation of Driver ability in Die Terranauten. A Riemenmann is a Driver whose psionic abilities have been amplified to such catastrophic levels that the body itself emits a constant field of lethal PSI radiation, fatal to any unshielded being in proximity. To contain this radiation, the Riemenmann must wear a full-body weave of golden straps -- the Riemen from which the title derives -- lined with Thingstone crystals that absorb and dampen PSI emissions. The Riemenmann exists beyond the conventional Driver hierarchy of Lodge Masters and Summacums: too powerful to function within a normal Lodge, too dangerous to operate without containment, and too valuable -- both as weapon and symbol -- to be ignored by any faction in the galactic struggle.

The title is inseparable from Llewellyn 709, the saga's second most prominent character, who appears as the Riemenmann across 53 of 99 booklets. His doppelganger Valhala 13, bred by the Gray Guards as a controlled duplicate, is the only other known Riemenmann in the saga. The term appears in 24 or more booklets and carries shifting connotations: revered title among the Terranauts, feared designation among their enemies, and -- in the darkest descriptions -- a label for "a PSI monstrosity, a human subjected to horrific experiments" (Booklet 043).

Etymology and Meaning

The word Riemenmann is a compound of the German Riemen ("strap" or "belt") and Mann ("man"). The name is purely descriptive: it identifies its bearer as "the man in the straps." Unlike the hierarchical titles of Lodge Master or Summacum, which denote earned rank within the Driver political structure, Riemenmann describes a physical condition -- the golden strap-weave that the bearer must wear at all times to prevent the uncontrolled emission of lethal PSI radiation.

The term functions differently depending on context:

• Among the Terranauts and Drivers: The Riemenmann is spoken of with a mixture of awe and sorrow. Llewellyn 709 is "the Riemenmann" -- the definite article conferring a singular, legendary status. Drivers recognize the Riemenmann as the most powerful among them, a being who has transcended normal PSI ability at the cost of his own humanity. The title carries connotations of sacrifice: the Riemenmann gave up his former identity (Mar-Estos) to become a living weapon for the cause.

• Among enemies: The Council of Corporations, the Gray Guards, and Max von Valdec view the Riemenmann as a strategic asset to be captured, studied, duplicated, or destroyed. Summacum Jorgez, the chief scientist at the Dead Spaces, objects to the transfer of imprisoned Drivers specifically because he wants to continue experimenting on Llewellyn 709 (Booklet 009). The Kaiser Corporation's Alpha-Order program on Sarym attempts to breed Riemenmanner -- super-Drivers of equivalent power under corporate control (Booklets 043, 045, 046).

• In the saga's glossaries: The term is defined with varying emphasis across different booklets, reflecting its multifaceted nature:
• "A Driver who wears golden straps to contain his lethal PSI radiation" (Booklet 001)
• "A Driver who wears special straps made of a PSI-dampening material to control their PSI radiation" (Booklet 015)
• "A person whose body is covered in golden straps to protect others from their PSI radiation" (Booklet 063)
• "A PSI monstrosity, a human subjected to horrific experiments" (Booklet 043)
• "A super-Driver, a PSI-monster created through inhuman experiments" (Booklet 046)
• "Genetically enhanced humans with powerful PSI abilities, often used as pilots" (Booklet 045)

The variation in these definitions tells its own story: from the neutral descriptive ("a Driver who wears straps") to the horrified ("a PSI monstrosity"), the Riemenmann is perceived differently depending on the observer's relationship to the person behind the straps.

The Transformation

How a Riemenmann Is Made

The process by which a human Driver becomes a Riemenmann is one of the saga's deliberate mysteries. What is known is that the transformation involves extreme PSI enhancement -- an amplification of psionic ability so radical that it reshapes the body, vastly increases psychic output, and renders the subject's natural PSI emissions lethal to those nearby. The descriptions across the saga suggest multiple pathways to this condition:

1. Voluntary or imposed enhancement: Llewellyn 709's transformation from Mar-Estos occurred at some point between c. 2475 and 2499 AD, under unknown circumstances. Whether he chose the transformation to serve the Terranaut cause or whether it was imposed upon him by outside forces remains one of the saga's central unsolved questions. What is certain is that the process destroyed his former identity so thoroughly that encounters with Mar-Estos's surviving consciousness are described as meeting "a former self" -- as if the pre-transformation person had died (Booklets 042, 061).

1. Genetic engineering and breeding: The Gray Guards' Alpha-Order program on Sarym represents the corporate attempt to manufacture Riemenmanner artificially. The program produces Super-Drivers through biochemical treatments, genetic engineering, and mental conditioning. The most successful product is Valhala 13, bred specifically as a duplicate of Llewellyn 709 and implanted with a mental Killer-Block ensuring obedience (Booklet 045). The program also produces beings like Ares 17, Artemis 11, Plutos 23, Prometheus 107, Phoenix 17, and Isis 24 -- though these are typically classified as "Super-Drivers" rather than Riemenmanner, suggesting that the Riemenmann condition represents a further extreme even beyond Super-Driver enhancement.

1. The horror interpretation: Booklets 043 and 046 describe the Riemenmann as "a PSI monstrosity, a human subjected to horrific experiments" and "a PSI-monster created through inhuman experiments." These descriptions, emerging from the Sarym arc where the Kaiser Corporation's breeding program is exposed, suggest that the creation of a Riemenmann involves suffering on a scale that even the saga's hardened characters find appalling.

The Cost of Transformation

The transformation into a Riemenmann exacts a devastating personal toll:

• Identity destruction: Mar-Estos was Growan terGorden's nephew, Myriam's companion, a Terranaut cell leader with a name, a family, a companion named Luzia, and a life of privilege and purpose. All of this was erased. When Llewellyn 709 stands beside Growan terGorden in Booklet 004, forming their alliance against Valdec, neither appears to recognize the other as family. The transformation did not merely enhance Mar-Estos's abilities; it annihilated the man he was.

• Physical alteration: The Riemenmann's body emits PSI radiation at levels that are immediately lethal to nearby unshielded humans. This necessitates the permanent wearing of the golden strap-weave -- a full-body containment system that is simultaneously armor, prison, and the most recognizable visual symbol in the saga. The straps are not merely worn; they are the Riemenmann's defining characteristic, inseparable from his identity as Llewellyn 709 and from his ability to exist among other people without killing them.

• Permanent isolation: The lethal PSI radiation means that the Riemenmann can never remove his containment straps in the presence of others without risking their lives. Every embrace, every handshake, every moment of human intimacy must be mediated through the barrier of the golden weave. The Riemenmann is, in the most literal sense, untouchable.

The Golden Straps

The golden strap-weave (Riemen) is the Riemenmann's defining physical feature -- a full-body containment system that absorbs and dampens the lethal PSI radiation emitted by the bearer. The straps serve multiple functions:

Construction and Materials

• The straps are described as golden in color and made of a PSI-dampening material (Booklet 015).
• The strap-weave is lined with Thingstones -- radioactive crystals from Stonehenge II that absorb PSI emissions (Booklet 054). The Thingstone lining acts as the primary dampening mechanism, channeling the Riemenmann's excess PSI energy into the crystalline lattice rather than allowing it to radiate into the surrounding environment.
• The strap-weave covers the bearer's entire body, giving the Riemenmann a distinctive, immediately recognizable appearance.

Functions

1. PSI containment: The primary function. Without the straps, the Riemenmann's PSI radiation is lethal to anyone nearby. The strap-weave reduces this emission to safe levels, allowing the Riemenmann to interact with other people, serve aboard ships, and function in society.

1. PSI modulation: The straps do not merely suppress the Riemenmann's abilities; they modulate them, allowing controlled use of psionic powers through the dampening matrix. The Riemenmann can project telepathy, exercise telekinesis, and participate in Lodge operations while wearing the straps -- but at a fraction of the power available without them.

1. Symbolic significance: The straps are the saga's most potent visual metaphor. They represent power held in check, gift inseparable from curse, and the sacrifice demanded by extraordinary ability. The Riemenmann's straps mirror the saga's central argument about Kaiser Force: that power which cannot be contained destroys everything it touches.

Removal of the Straps

When the Riemenmann removes the straps, the results are catastrophic. The most dramatic instance occurs in Booklet 045, "Llewellyn's Gambit," when Llewellyn 709, cornered by Gray Guard forces on Stonehenge II, removes his PSI-dampening straps and unleashes a devastating PSI-storm that causes chaos, distorts reality, and overwhelms all nearby combatants. Only Valhala 13, protected by his own strap-weave, is able to approach and subdue him.

A similar event occurs in Booklet 001, when Llewellyn unleashes a PSI storm that paralyzes the Syrtian government troops on Syrta -- though in this case, the extent of strap removal is not explicitly described. The implication is consistent: the Riemenmann without straps is a force of nature, a walking catastrophe whose PSI output can incapacitate armies and warp reality itself. This is what makes the Riemenmann simultaneously the Terranauts' greatest asset and their most dangerous liability.

Abilities

The Riemenmann possesses psionic abilities far beyond those of ordinary Drivers, Lodge Masters, or even most Super-Drivers. The following abilities are demonstrated by Llewellyn 709 across the saga:

Psionic Abilities

• Galaxy-wide telepathy: In Booklet 001, Llewellyn sends a telepathic message across the entire galaxy, calling all Drivers to Syrta and declaring David terGorden the Heir of Power. This act -- requiring psionic range and power beyond anything a normal Driver or even a Super-Lodge can achieve -- ignites the rebellion that defines the saga.

• Telekinesis at extreme scale: In Booklet 075, Llewellyn reprograms the Gray Guard base's computer systems through telekinetic manipulation and redirects Kaiser Force tugs to plunge into a Black Hole -- all through force of mind alone.

• Psionic combat supremacy: Llewellyn defeats Ares 17, an engineered Super-Driver specifically designed as a psionic weapon, in direct psionic duel (Booklet 036). He also thwarts an Entity on Hephaistos and rescues Jana (Booklet 093).

• PSI storms: When uncontained, the Riemenmann generates reality-distorting psionic storms that affect everything in the vicinity. These storms can incapacitate armies (Booklet 001), cause chaos and structural destruction (Booklet 045), and distort the boundary between the physical and psionic realms.

• PSI shielding and Lodge operations: Despite operating outside the normal Lodge structure, the Riemenmann can lead and power Driver lodges. Llewellyn powers the CYGNI's escape from Argus (Booklet 026), leads the lodge aboard the JAMES COOK (Booklets 090-093), and participates in combined psionic operations throughout the saga.

Navigation and Piloting

Multiple booklet glossaries describe the Riemenmann as "a pilot skilled in navigating Space II" (Booklet 029) and note that Riemenmanner are "often used as pilots" (Booklet 045). The Riemenmann's extreme PSI power makes him uniquely suited for the most dangerous Space II transits, where a normal Driver lodge might fail. Llewellyn navigates the MIDAS past a Black Hole (Booklet 014), powers the CYGNI through hostile space, and survives conditions that would destroy ordinary Drivers.

Survivability

The Riemenmann demonstrates extraordinary physical and psionic resilience:

• Survives the MIDAS catastrophe that kills or transforms most of the crew (Booklets 010-014)
• Escapes the Dead Spaces, a PSI-shielded prison designed to strip Drivers of their abilities (Booklet 009)
• Survives deep-sleep imprisonment (Booklets 045-046)
• Endures crash-landings on Hobo (014), Sarym (061, 063), and Arioch (083)
• Survives KF-emission coma (Booklet 095) and recovers in the Reality Switch (Booklet 097)

The Dead Spaces escape is particularly significant: the facility's PSI-Shield is designed to strip PSI powers from imprisoned Drivers, yet Llewellyn retains enough ability to break through bricked-up passages and fight the "Dark Ones" -- maddened prisoners who have succumbed to the prison's psychological effects. Where ordinary Drivers are broken by the Dead Spaces, the Riemenmann endures.

The Riemenmann Outside the Lodge System

A critical distinction sets the Riemenmann apart from other Driver ranks: the Riemenmann does not fit within the conventional Lodge hierarchy. While Lodge Masters lead lodges of 5 to 12 Drivers through Space II, and Summacums govern Driver political affairs from the Council of Lodge Masters, the Riemenmann exists outside and above these structures.

This is a function of necessity. The Riemenmann's lethal PSI radiation makes normal Lodge integration impossible -- a Lodge Master works in intimate psychic contact with every member of the lodge, a proximity that the Riemenmann's emissions would render fatal without his containment straps. Even with the straps, the Riemenmann's PSI output is so overwhelming that it can dominate or disrupt the delicate psychic balance of a working Lodge.

Instead, the Riemenmann operates as:

• A one-man strategic weapon: Capable of feats no Lodge can achieve -- galaxy-spanning telepathy, reality-distorting PSI storms, defeat of engineered super-weapons in single combat.
• A Lodge amplifier: When the Riemenmann chooses to participate in Lodge operations, he provides psionic power far beyond what any individual Lodge Master contributes. His presence aboard a ship like the CYGNI or JAMES COOK gives the Terranauts a decisive edge in Space II navigation and combat.
• An independent operator: Throughout the saga, Llewellyn frequently acts alone or in small groups rather than within a full Lodge structure -- leading the Dead Spaces escape (009), investigating Stonehenge II solo (045), commanding the IRMINSUL assault on Finstermann (075). The Riemenmann does not need a Lodge to function; the Lodge needs the Riemenmann.

Known Riemenmanner

Llewellyn 709 -- The Riemenmann

Llewellyn 709 is the definitive Riemenmann -- so much so that the title and the man are effectively synonymous. Born as Mar-Estos, nephew of Growan terGorden and companion of Myriam, he was transformed into a Riemenmann at some unknown point between c. 2475 and 2499 AD. The transformation destroyed his former identity and created the golden-strapped figure who would ignite the Driver rebellion with a galaxy-wide PSI call (Booklet 001), fight beside David terGorden across 53 booklets, and confront Max von Valdec in the void when reality itself dissolves (Booklet 098).

Llewellyn's search for his lost past -- his vision of Stonehenge II (Booklet 045), his encounter with Mar-Estos's consciousness in the Maritime Coral City (Booklet 061) -- suggests that even the Riemenmann himself does not fully understand what was done to him or why. The golden straps contain his power, but they also contain the silence where his memories used to be.

For the full biography, see Llewellyn 709.

Valhala 13 -- The False Riemenmann

Valhala 13 is the Gray Guards' answer to Llewellyn 709 -- a Riemenmann bred through the Alpha-Order genetic enhancement program, designed as a perfect physical and psionic duplicate of Llewellyn, and implanted with a mental block (Killer-Block) that forces suicidal obedience if he defies his controllers.

Valhala 13 is trained on Stonehenge II by PSI-Expert Sartyra Fuji under the supervision of Queen Ishiya. He is "plagued by fragmented memories" and "fears the mental block implanted in his mind" (Booklet 045), suggesting that the artificial creation of a Riemenmann is even more psychologically devastating than whatever process transformed Mar-Estos. When Llewellyn removes his straps on Stonehenge II, Valhala -- protected by his own strap-weave -- is the only being present able to approach and subdue him, demonstrating that his psionic containment is equivalent to the original.

Valhala successfully impersonates Llewellyn and infiltrates the Terranauts (Booklet 045), attacks and seemingly kills several Terranauts including David terGorden on Rorqual (Booklet 046), and is forced by Queen Ishiya to help spread the Hate Plague (Booklet 048). His arc ends when David, Llewellyn, and Lyda Mar sacrifice him to close a dimensional rift near a Black Hole (Booklet 048) -- a grim resolution that treats the false Riemenmann as expendable, a weapon to be used and discarded.

Valhala 13's existence proves that the Council of Corporations possesses the knowledge and technology to create Riemenmanner, but his tormented psychology and ultimate fate demonstrate the limits of manufactured power. Where Llewellyn's transformation -- however mysterious -- produced a figure of enduring loyalty and moral clarity, Valhala is a broken weapon wielded by handlers who do not understand what they have made.

Historical Context

Origins in the Driver Caste

The Riemenmann designation exists within the broader context of the Driver caste system. Drivers are PSI-gifted humans who navigate spacecraft through Space II, organized into Lodges under Lodge Masters, with the elite Summacums governing from the Council of Lodge Masters on Zoe. Within this hierarchy, PSI ability exists on a spectrum: from the average Driver who serves competently in a Lodge, through the exceptional Lodge Masters who coordinate them, to the extremely rare individuals whose power exceeds all institutional categories.

The Riemenmann represents the absolute extreme of this spectrum -- a Driver whose PSI enhancement has passed the threshold where the body becomes a lethal emitter, requiring permanent physical containment. The title is not awarded through political process or earned through seniority; it is the name for what a Driver becomes when enhancement goes beyond what any human body was meant to hold.

The Alpha-Order and Corporate Reproduction

The Kaiser Corporation's Alpha-Order program on Sarym represents the most systematic attempt to understand and replicate the Riemenmann condition. Operating under Hermano Lotz and later exposed in Booklets 043-046, the program subjects Drivers to genetic engineering, biochemical enhancement, and mental conditioning in an effort to produce controllable super-Drivers and ultimately a controllable Riemenmann. The program succeeds in creating Valhala 13 and a range of Super-Drivers (Ares 17, Artemis 11, Plutos 23, Prometheus 107, Phoenix 17, Isis 24), but the moral cost is extreme -- the saga describes the program's products as "PSI monstrosities" and the Riemenmann as a being "created through inhuman experiments."

The distinction between the Alpha-Order's products and Llewellyn 709 is telling. Llewellyn's transformation, however it occurred, produced a person of complete moral autonomy -- one who fights for the cause he believes in, leads with tactical brilliance, and maintains ethical boundaries even in the heat of war (countermanding Dime Mow's order to massacre Gray Guard prisoners in Booklet 075). The Alpha-Order's Riemenmann, Valhala 13, is a tormented puppet controlled by mental blocks, fragmented memories, and the threat of implanted suicide. Corporate power can reproduce the condition but not the character.

The Riemenmann and the Terranauts

Within the Terranauts, the Riemenmann occupies a unique position. He is not formally the leader -- that role belongs variously to David terGorden, Asen-Ger, and the collective Terranaut council -- but his power and presence give him an authority that transcends formal rank. When Llewellyn speaks, the Terranauts listen. When he disagrees with strategy (as when he advocates breaking apart the corporations in Booklet 050, against Asen-Ger's willingness to compromise), his dissent carries enormous weight. When he acts unilaterally (investigating Stonehenge II in Booklet 045, commanding the IRMINSUL assault in Booklet 075), no one stops him.

This informal supremacy reflects the Riemenmann's position in Driver mythology: he is not a political figure but a force of nature made flesh, a living demonstration of what Driver power can become when all limits are removed. The Terranauts do not command the Riemenmann; they ally with him.

How Others View the Riemenmann

The Riemenmann is perceived differently by every faction and character who encounters him:

The Terranauts

The Terranauts regard the Riemenmann with deep respect and a measure of awe. David terGorden trusts him implicitly. Lyda Mar is the one who first senses the Valhala 13 imposture (Booklet 046), demonstrating an intimate familiarity with the Riemenmann's true psionic signature. Claude Farrell, Angila Fraim, and the CYGNI crew follow him without question. Even Asen-Ger, who frequently disagrees with Llewellyn's militant stance, never challenges his status as the Terranauts' most powerful individual.

The Council of Corporations

The Gray Guards

The Gray Guards fear the Riemenmann. On Stonehenge II, Queen Ishiya orders his capture alive precisely because she understands the danger of engaging him in open combat. When Llewellyn removes his straps, the resulting PSI-storm overwhelms every Gray Guard present (Booklet 045). The production of Valhala 13 -- a Riemenmann under Gray Guard control -- represents the Guards' attempt to neutralize the threat by creating their own version of it.

Other Drivers

Among ordinary Drivers, the Riemenmann is a legendary figure. When Llewellyn sends his galaxy-wide PSI call in Booklet 001, the entire Driver fleet responds -- converging on Syrta from across the galaxy. This response reflects not merely the political content of the message but the sheer psionic authority behind it: every Driver who receives that call knows it comes from a being of incomprehensible power. The Riemenmann is, for the Driver caste, proof of what their gift can become -- and a warning of what it costs.

Thematic Significance

Power Contained

The Riemenmann is the saga's most concentrated expression of the tension between power and restraint. The golden straps are a physical embodiment of the philosophical question at the heart of Die Terranauten: what happens when the capacity for creation and destruction are fused in a single being? Kaiser Force tears open Space II, enabling faster-than-light travel but accelerating entropy and threatening cosmic stability. The Riemenmann's body does the same thing on a personal scale: his PSI power enables feats that save civilizations, but uncontained, it destroys everything it touches.

Llewellyn's straps are not a cure. They are a compromise -- a fragile barrier between the Riemenmann's potential and its consequences. When the barrier breaks (Booklets 001, 045), the results are as devastating as any Kaiser Force breach. The saga's argument is clear: the most dangerous powers are those that cannot be fully contained, only temporarily restrained.

The Biological Kaiser Force

This parallel is made explicit in the Llewellyn 709 character page: "Llewellyn is, in a sense, a biological Kaiser Force -- immense potential held in check by fragile bonds." Just as Kaiser Force rips open the membrane between Space I and Space II through brute technological force, the Riemenmann's body radiates psionic energy that warps the boundary between physical reality and the PSI dimension. Both represent humanity's capacity to channel cosmic forces beyond its ability to fully control them.

The critical difference is intentionality. Kaiser Force is a corporate technology designed to exploit Space II for profit, indifferent to the entropic consequences. The Riemenmann chooses to constrain himself -- to wear the straps, to fight within limits, to serve a cause rather than dominate through raw power. Llewellyn's militancy has moral boundaries (Booklet 075); his power has self-imposed restraint (the straps). This is what separates the Riemenmann from Max von Valdec: both wield world-breaking power, but only one chooses to hold back.

Sacrifice and Identity

The transformation into a Riemenmann destroys the person who existed before. Mar-Estos -- the name, the family, the relationships, the memories -- is consumed in the process. What emerges is something more powerful but fundamentally diminished: a being who can send telepathic messages across the galaxy but cannot remember his own uncle's face. The golden straps contain PSI radiation, but they also wrap around an absence -- the space where a complete human identity used to be.

Llewellyn's search for his past (Booklet 045) and his encounter with Mar-Estos's PSI echo in the Maritime Coral City (Booklet 061) are the saga's most poignant expressions of this loss. The Riemenmann who confronts the consciousness of the man he used to be is meeting a stranger who shares his soul. The straps cannot restore what the transformation took.

The Singular and the Duplicate

The existence of Valhala 13 raises the question of whether the Riemenmann is a unique phenomenon or a reproducible condition. The answer the saga provides is characteristically ambiguous: the body can be duplicated, the power can be replicated, but the person cannot be copied. Valhala 13 has Llewellyn's face, Llewellyn's straps, and Llewellyn's psionic signature -- but he is a broken, tormented puppet controlled by mental blocks and the threat of forced suicide. The Alpha-Order can manufacture a Riemenmann's body; it cannot manufacture his will.

The resolution of the doppelganger arc -- Valhala's sacrifice to close the dimensional rift (Booklet 048) -- treats the false Riemenmann as ultimately expendable. The true Riemenmann endures. The saga's position is clear: what makes the Riemenmann significant is not the power but the person who wields it.
