Tarvon the Undying

While Omega the most feared being in The Terminus, perhaps in all existence, Taarvon the Undying and his Shadowbane are not to be taken lightly (so to speak). After a long career as a superhero on his native world, Taarvon became a student of the Alphian Philothume. Tales of the dark places, the Shadows into which the Alphians never ventured, fascinated Taarvon. He wanted to know more about the Shadow World.
Knowing the Alphians would never approve, Taarvon began his own studies. Soon he came to hear voices in the shadows, telling him he was destined to be master of shadows. All he needed to do was steal the SourceBook and bring it to the Shadow World, and the darkness would reward him.
One day, he got his chance. Along with his master, Philothume, Taarvon was a guest at the great world-library, where he was allowed access to all books except those in the Archivist’s personal collection (which included, of course, the SourceBook). Although the betrayal of Omega had not yet taken place, Tomen was still the most guarded of all Alphians. He caught Taarvon in the act of stealing the Book, and he punished him by chaining him to a desk and forcing him to write by hand a book detailing every sin he’d ever committed—and then copying it a thousand times.
However, such punishments often bear unintended fruit, and oftentimes those fruits are poison. Servants of the Shadow World had already infiltrated Taarvon’s shadow, servants even Tomen could not see. As their host scribbled, they skittered through the library, gathered knowledge from forbidden tomes, and whispered secrets into Taarvon’s ears. The shadows could not reach the SourceBook itself—it shone too brightly for them to approach—but they learned sorceries most fell, which utterly corrupted the young philosopher-hero.
Finally, Taarvon finished the thousandth book, and as he rested, he felt a great change come over the universe. Tomen beheld the DoomCoil’s triumph and shuddered. Philothume challenged the new order and was struck down; he was one of many Alphians stretched into the Ouroboros Skin.
“You will need to find a new master,” Tomen remarked acidly, as he returned the philosopher to Edanth. “Although I say with complete confidence, this will be the easiest task of your life.”
Taarvon was too bewildered by the changes to Edanth to read much into the remark. When Omega stepped forward and demanded his allegiance, he gave it, but neither trusted the other. Taarvon bided his time, and he was finally rewarded with what he sought. To ensure his loyalty, Omega took him to see the Doom-Coil. But the shadows cloaked his mind, even while they lusted after the god-machine’s power.
Taarvon soon betrayed Omega and fled to the Last Shadow, a world where he built a great dark citadel. He summoned creatures from the Shadow World as his servants and challenged Omega for control of the Doom-Coil. Time and again, he’s been driven back, however Taarvon hopes that soon, the victory will be his. How sweet will be the day when the defeated Omega kneels at his feet as the shadows finally devour him!
