"They encounter the consciousness of Mar-Estos, a former self of Llewellyn 709."
-- Booklet 042, "The Gatherer"
Mar-Estos is the original identity of Llewellyn 709, the legendary Riemenmann and second most prominent character in the Die Terranauten saga. As Mar-Estos, he was the nephew of Growan terGorden, a leader within the Terranaut underground, and the closest ally of Myriam during the critical period of the Yggdrasil Project at Ultima Thule (c. 2475 AD). His story bridges the saga's prequel-era backstory and its main narrative: he begins as a privileged member of the terGorden Dynasty who risks everything for the Driver cause, and ends -- after a mysterious and devastating transformation -- as the golden-strapped super-Driver whose galaxy-wide PSI call ignites the rebellion that defines the saga.
Mar-Estos appears directly in two flashback booklets (030, 031), is referenced in three others (042, 044, 061), and his consciousness is encountered as a PSI echo in the Maritime Coral City on Sarym. His disappearance after dealing with Clint Gayheen and his subsequent transformation into a Riemenmann constitute one of the saga's deliberate mysteries.
Biography
Family and Position at Biotroniks (c. 2475)
Mar-Estos was the nephew of Growan terGorden, the General-Manager of the Biotroniks Corporation -- the most powerful enterprise in the Council of Corporations, which held a monopoly on the Mistletoe Blossoms essential for Driver space travel. This family connection placed Mar-Estos at the heart of Biotroniks' power structure in Ultima Thule, Greenland. He owned a luxury glider, the ASTRA, and lived a life of outward privilege.
Yet beneath this comfortable surface, Mar-Estos was a committed revolutionary. He was a Driver and a leader within the Terranauts, the underground resistance movement dedicated to freeing Drivers from corporate tyranny and challenging the Manags' stranglehold on interstellar travel. His position as Growan's nephew gave him access and cover that made him invaluable to the cause.
Mar-Estos had a personal companion named Luzia, and had promised her a visit to the Pankaldis family in Brazil -- a detail that hints at a private life beyond the political intrigues that consumed him.
Introducing Myriam to Biotroniks
Mar-Estos's most consequential act was introducing Myriam to his uncle Growan terGorden. Myriam was a brilliant biologist and secret Terranaut operative, whom Mar-Estos brought into the Biotroniks Corporation as a coordinator for the Yggdrasil Project -- the research initiative studying Yggdrasil, the primeval tree, and its mistletoe blossoms in the Holy Valley of Odrodir. Growan, impressed by her abilities, hired her immediately (Booklet 030).
This introduction was both genuine and calculated. Mar-Estos recognized Myriam's extraordinary affinity for Yggdrasil and understood that placing her within Biotroniks would advance the Terranaut cause. By positioning a fellow operative at the highest level of the corporation's most sensitive research project, he created a channel of influence that the underground had never before achieved.
The Terranaut Cell at Ultima Thule
With Myriam embedded at Biotroniks, Mar-Estos organized a clandestine cell of Terranauts operating within and around the corporation. He and Myriam held secret meetings with Algol Kuhn, Santiago Lema, Carlos Lema, Shadow, and Jonsson to discuss their plans to influence Biotroniks from within and challenge the power of the Manags and the Council of Corporations (Booklet 030).
The cell operated under constant danger. Clint Gayheen, Growan's security chief -- and, unknown to all, a secret agent of Max von Valdec and the Kaiser Corporation -- watched the group with suspicion and reported their activities to Growan. Growan, however, dismissed Gayheen's concerns about his nephew and the Drivers, a misjudgment that would prove both beneficial and ultimately tragic.
The Rescue of Myriam
Myriam's double life quickly drew lethal attention. She was attacked and abducted by masked men -- an operation later traced to Clint Gayheen -- and tortured by an unseen figure demanding information about her origins and her connection to Yggdrasil. When Mar-Estos and the Terranauts discovered Myriam was missing, they launched an immediate rescue mission. Algol Kuhn was killed during the operation, but Myriam was saved and the Gray Guards responsible were eliminated (Booklet 030).
This event deepened the bond between Mar-Estos and Myriam and hardened his resolve against Gayheen. When Growan terGorden asked Mar-Estos about Myriam's background, Mar-Estos defended her loyalty while keeping her Terranaut affiliations hidden.
Confrontation with Gayheen
The conflict between Mar-Estos and Clint Gayheen escalated steadily. Gayheen confronted Mar-Estos directly, warning him to stay away from Myriam. Mar-Estos responded by stunning Gayheen with a weapon and leaving him outside his own apartment -- a brazen act of defiance that demonstrated his willingness to take physical action against the security chief (Booklet 031).
When Mar-Estos brought his concerns about Myriam's increasing isolation to Growan, his uncle dismissed them, saying the restrictions were "for her own good." This rebuff revealed the limits of Mar-Estos's influence over Growan and the widening gap between the two men.
Thwarting Hados's Experiment
Hados, an Arbiter secretly working for Max von Valdec, arrived at the Biotroniks research center and attempted to inject Drivers with a substance purported to enhance their PSI abilities. Mar-Estos, together with Merlin III and Shadow, intervened and stopped the experiment. Merlin revealed that the substance was lethal and that Hados was a Valdec agent. One of the Drivers who had been injected, Elko, was saved by Merlin. Hados was killed, and his death was covered up as an accident (Booklet 031).This episode demonstrated Mar-Estos's protective instincts toward the Drivers under his care and his growing effectiveness as a Terranaut leader.
Exposing Gayheen's Treachery
Mar-Estos's most critical achievement as Mar-Estos came when he discovered that Clint Gayheen had been using Myriam's ID card to access Growan terGorden's Council Chamber and had been in direct communication with Max von Valdec, actively working to undermine Biotroniks from within. Mar-Estos brought this evidence to Growan, who -- finally confronted with undeniable proof -- gave his nephew full authority to deal with the traitor (Booklet 031).
Mar-Estos captured Gayheen, who was presumably killed. Growan then traveled to Berlin to confront Valdec directly, accusing him of treachery.
Disappearance
After his mission against Gayheen, Mar-Estos disappeared. The saga states simply that he vanished after "his flight with Gayheen" -- leaving open the question of what happened during or immediately after the confrontation (Booklet 031).
This disappearance marks the end of Mar-Estos as a named, active character. What followed -- at some unknown point between c. 2475 and 2499 -- was the transformation that turned him into Llewellyn 709, the Riemenmann.
The Transformation into Llewellyn 709
The circumstances of Mar-Estos's transformation into a Riemenmann remain one of the saga's deliberate and most profound mysteries. The process of extreme PSI enhancement reshaped his body, vastly amplified his psionic abilities, and left him emitting lethal PSI radiation that required constant containment through the golden strap-weave that became his defining characteristic. The transformation was so complete that it effectively created a new person: when characters later encounter the consciousness of Mar-Estos, they describe it as meeting "a former self" of Llewellyn 709, as if speaking of the dead (Booklet 042).
Whether the transformation was voluntary -- undertaken to create a weapon powerful enough to serve the Terranaut cause -- or imposed upon him by unknown forces, the saga does not say. What is certain is that it cost Mar-Estos his name, his family connections, his personal relationships, and apparently much of his memory of his former life. The man who had been Growan terGorden's nephew, Myriam's trusted companion, and a Terranaut cell leader was reborn as a figure of devastating power and terrible isolation.
By 2499, when the saga opens in Booklet 001, Llewellyn 709 is already a legendary super-Driver on Syrta. There is no indication that he recognizes himself as the nephew of Growan terGorden or that Growan recognizes him as Mar-Estos when they form their desperate alliance in Booklet 004. The family connection is simply gone -- erased by the transformation.
The PSI Echo: Mar-Estos in the Maritime Coral City
Though Mar-Estos ceases to exist as a living identity after his transformation, his consciousness survives as a PSI echo within the Maritime Coral City on Sarym -- a vast coral structure that serves as a central control element for the planet's Bio-PSI system.
First Encounter (Booklet 042)
In "The Gatherer," Lyda Mar and Damon Credock use Dream-hooks to synchronize with the presence inhabiting the Maritime Coral City, merging their minds in the process. During this communion, they encounter the consciousness of Mar-Estos, identified as "a former self of Llewellyn 709." This encounter reveals that PSI-experiments were conducted by Hermano Lotz at a secret Gray station on Sarym, and provides crucial information about the connection between Llewellyn's past and the planet's PSI network (Booklet 042).
It is during this encounter that Lyda Mar and Damon Credock conceive Aura Damona Mar, their telepathically gifted daughter -- suggesting that Mar-Estos's lingering consciousness catalyzed or facilitated this extraordinary event.
Second Encounter (Booklet 061)
When Llewellyn 709 himself enters the Maritime Coral City alongside Lyda Mar in "Death Awaits on Sarym," he encounters an echo of his own past self -- Mar-Estos. This moment is one of the saga's most emotionally charged: the Riemenmann, the weapon of the revolution, confronting the man he used to be. The PSI-aura preserves Mar-Estos's identity like an archaeological stratum, accessible to those with sufficient psionic sensitivity but forever separated from the living Llewellyn by the chasm of transformation (Booklet 061).
The Hate Plague Connection
Mar-Estos's identity plays a sinister role in Hermano Lotz's biological warfare scheme. On Sarym, Lotz operates a secret research station where he imprisons Lyda Mar, Ennerk Prime, and Onnegart Vangralen, subjecting them to psycho-interrogation to learn the location of Rorqual, the Terranaut base. Lotz then infects the Terranauts with a virus -- the Hate Plague -- designed to activate upon contact with Mar-Estos (i.e., Llewellyn 709) on Rorqual (Booklet 044).
The virus was engineered to use Llewellyn's unique PSI signature -- still linked to his Mar-Estos identity at a biological level -- as its activation trigger. This detail confirms that despite the Riemenmann transformation, some fundamental aspect of Mar-Estos's original PSI fingerprint persists within Llewellyn 709. The Hate Plague causes uncontrollable rage and madness, and its spread aboard the CYGNI and on Rorqual drives much of the mid-saga crisis (Booklets 044, 046, 047, 048).
Lotz orchestrated a staged prison break, allowing the Terranauts to escape and unwittingly carry the virus back to their base. The scheme was approved by Max von Valdec, who anticipated that the Hate Plague would force the Terranauts into surrender. The fact that Valdec's scientists could weaponize Mar-Estos's PSI identity suggests that the Gray Guard intelligence apparatus had knowledge of the connection between Mar-Estos and Llewellyn 709 -- knowledge that the Terranauts themselves may not have possessed at that time.

Relationships
Family
| Character | Relationship | Notes |
|---|---|---|
| Growan terGorden | Uncle | Mar-Estos was Growan's nephew, operating within Biotroniks under the protection of his family name. Their relationship was complex: Growan trusted Mar-Estos enough to give him authority over Gayheen, yet dismissed his warnings about Myriam's safety. After Mar-Estos's transformation, this family bond was never again acknowledged. |
| David terGorden | Cousin (Growan's son) | David was born shortly before Mar-Estos's disappearance. As Llewellyn 709, Mar-Estos would become David's closest companion and most dedicated protector -- never revealing (and perhaps not remembering) that they were family. |
| Luzia | Companion | Mar-Estos's personal companion during the Ultima Thule period. Her fate after his disappearance is unknown. |
Allies
| Character | Relationship | Notes |
|---|---|---|
| Myriam | Closest ally and co-conspirator | Mar-Estos introduced Myriam to Biotroniks, organized her Terranaut activities, rescued her from abduction, and defended her against Gayheen's machinations. He was her primary protector and the person who made her infiltration of Biotroniks possible. |
| Merlin (Merlin III) | Ally | Worked together to stop Hados's lethal experiment on the Drivers. Merlin protected Myriam alongside Mar-Estos. |
| Algol Kuhn | Fellow Terranaut | Member of Mar-Estos's cell, killed during the rescue of Myriam. |
| Santiago Lema | Fellow Terranaut | Member of the Ultima Thule cell, participated in Myriam's rescue. |
| Carlos Lema | Fellow Terranaut | Santiago's brother, member of the cell. |
| Shadow | Fellow Terranaut | Key operative in the cell; helped stop Hados's experiment. Later fatally wounded by a Gray Guard while defending Myriam. |
| Jonsson | Fellow Terranaut (compromised) | Member of the cell who was coerced by Gayheen into becoming an informant, reporting on Myriam's activities. |
| Asen-Ger | Terranaut ally | Visited Ultima Thule and revealed himself as a Terranaut to Mar-Estos's circle. Warned about the Kaiser Force. |
Antagonists
| Character | Relationship | Notes |
|---|---|---|
| Clint Gayheen | Primary enemy | Growan's security chief and Valdec's spy. Gayheen attempted to isolate Myriam, abducted and tortured her, and warned Mar-Estos to stay away. Mar-Estos ultimately exposed his treachery and captured him. |
| Max von Valdec | Distant enemy | The power behind Gayheen's machinations. Valdec's scientists later weaponized Mar-Estos's PSI identity for the Hate Plague virus. |
| Hados | Antagonist | Valdec's agent who attempted to inject Drivers with a lethal substance; stopped by Mar-Estos, Merlin, and Shadow. |

Themes and Significance
The Man Before the Weapon
Mar-Estos's story is the origin story of Llewellyn 709 -- and it is a story of loss. As Mar-Estos, the future Riemenmann was a complete person: he had a family (Growan), a companion (Luzia), a circle of friends and comrades (the Terranaut cell), a home (Ultima Thule), and an identity rooted in both privilege and principle. He chose to use his position within the terGorden dynasty to fight for Driver liberation, running covert operations under his uncle's nose. He was brave (rescuing Myriam, confronting Gayheen), clever (exposing Gayheen's treachery through evidence of his unauthorized Council Chamber access), and loyal (defending Myriam, protecting the Drivers from Hados).
All of this was erased by the transformation into a Riemenmann. The golden straps that define Llewellyn 709 contain lethal PSI radiation, but they also contain a deeper truth: beneath them lies a man who lost everything he was in order to become everything the revolution needed.
The Bridge Between Eras
Mar-Estos is the narrative bridge connecting the prequel era (the Yggdrasil Project, Growan and Myriam's marriage, the birth of David) to the main saga (the Driver rebellion, the Terranaut war). Without Mar-Estos, Myriam would never have entered Biotroniks. Without Myriam, the Yggdrasil Project would never have produced the Book Myriam or the child prophesied to free humanity. And without Mar-Estos's transformation into Llewellyn 709, there would have been no galaxy-wide PSI call in Booklet 001 and no rebellion at all.
He is the hidden link in the saga's chain of causation: the man who set the prequel's events in motion and who then, in a transformed state, set the main saga's events in motion as well.
The Cost of Transformation
The transformation from Mar-Estos to Llewellyn 709 is the saga's starkest illustration of the price demanded by power. The Riemenmann is immeasurably more powerful than Mar-Estos ever was -- capable of sending telepathic messages across the galaxy, defeating engineered super-Drivers in psionic combat, and destroying entire military installations through force of will. But this power came at the cost of identity itself. The man who was Growan's nephew stands beside Growan in Booklet 004 as they form their alliance against Valdec, and neither appears to recognize the other as family. The man who protected Myriam becomes David's greatest protector -- never knowing, perhaps, that David is the son of the woman he once fought to save.
Llewellyn's search for his past on Stonehenge II (Booklet 045) and his encounter with Mar-Estos's echo in the Maritime Coral City (Booklet 061) suggest a longing for the identity he sacrificed. The PSI echo is all that remains of Mar-Estos -- a consciousness preserved in coral and dream-hooks, encountered by strangers who recognize it as "a former self" but cannot restore it to the man it once was.
The Unbroken Thread
Despite the totality of the transformation, one thread connects Mar-Estos to Llewellyn 709 beyond all disguise: his devotion to the Driver cause. As Mar-Estos, he risked his privileged position to lead Terranauts. As Llewellyn 709, he risks his life in every booklet for the same cause. The body changed, the name changed, the memories may have been lost -- but the fire that drove Mar-Estos into the underground is the same fire that drives the Riemenmann into battle after battle for fifty-three booklets. In this sense, Mar-Estos never truly disappeared. He was forged into something harder, sharper, and more terrible -- but the core remained.
