Genetically engineered by the Shadolings of Imortalu, Wro and Klaracor are the last of their kin. The Nervewalkers’ transition from symbiotic microbial colonies into a warrior people gave Wro and Klaracor their initial undying goal: to eliminate all Glolings and Greylings. For year upon year they smote trails through the world, leaving bodies and fire in their wake. Wro and Klaracor distantly remember their lives before and during the war for which they were made.

Wro and Klaracor shared a bond, being comrades in the war and depending on one another for survival. Towards the end of the war, they became separated. Klaracor found refuge in the body of a Shadoling scientist councilor who sheltered her from the purge, which was the Shadolings’ attempt to eradicate the Nervewalkers before their creation wiped out all three races. Klaracor would become a powerful supervillain in tandem with the councilman, who would eventually become the supervillain Zorb. Wro managed to board the ship escaping Immortalu in the moments before the purge was released.

Wro tore through the crew of the ship, burning through everyone there for what they had done to her people and their planet. Eventually, she was left with only a few survivors, and she rationed her supply of life support. Even so, she gravely underestimated the time it would take for the ship to reach its destination, the inhabited world of Myriad. By the time the ship arrived, Wro was nothing more than a faint spark smoldering in the last living organism in the ship: a shadoling known as Exer. Though utterly powerless against Wro and terrified of her, Exer maintained enough control of his mind to telepathically converse with Wro while she inhabited him. This was not the first time Wro had experienced this, but Exer was the first of her hosts for which she cared.

While Exer’s life grew weaker, Wro wittled herself down to just a few cells to avoid depleting his metabolism. Both severely weakened, Wro and Exer had developed a kind of relationship that challenged Wro’s will to live. Upon arriving at Myriad, Exer used the last of his own strength to pilot the ship to safety. By the time the locals entered the ship, Wro had reluctantly taken Exer’s final breaths to accumulate into a desperate wisp of her cells trickling down the halls of the ship.

Finally, she found a Myriadi host. Alive again, Wro attempted to keep a low profile, hidden from host to host. She explored the world of Myriad, which would be the first of her many homes away from Imortalu.

For countless lifetimes, Wro lived in the margins of societies. Sometimes, she would intervene by possessing disadvantaged individuals and wreaking havoc on abusers of power. Wro was virtually unstoppable. Emperors fell by her countless hosts’ hands. Wro’s violence had not gone unnoticed. When she came to a technologically advanced world frequented by the Purgatoran Guard, Wro took her confidence for granted. She possessed members of a high council of planets, studied their deeds, and murdered some of them. The Purgatoran guard used everything at their disposal to detain Wro, and eventually succeeded. They imprisoned her on a ship sent to Purgator, with a supply of criminals on death row, the first group of many she would be fed during her indefinite sentence at Ground Zero, a facility created during her transport in the very center of Purgator, specifically for her.

The Purgatoran Guard would use Wro as an executioner for death row prisoners for an amount of time utterly lost to her indefinite lifespan. Wro’s conscience grew dormant as the lifetimes wore on. The amount of time that elapsed by the time Wro meets Zea and begins a new chapter of her life is indeterminable.
