Once a Solar Vulpkanin, Tess' body was slowly eaten from the inside out by his own corrupted Neural Implant Framework, and is now composed entirely of biomechanical nanite slurry. Formerly unstable and prone to sadist impulses towards cannibalism, the additional tails he grew over the course of his transformation have fully stabilized his mind and body.

He is the Captain and Owner of the NSB Argent Whispers, though typically delegates the role in favor of remaining with his large family and many children in his deep space habitat. While mostly supported through his mercenary company's enterprises, he also cultivates and sells rare or otherwise extinct raw materials on the black market, from stock he and his have collected over the course of their adventures.

Tess is slow to anger, but often explosive when pushed. He does not relish in causing suffering, but is known to often play tricks at the expense of others. While not particularly greedy nor gluttonous, he will sometimes covet specific things that catch his fancy and work to possess them at nearly any cost. He is intensely protective of what he considers his, guarding it fiercely regardless of others' opinions or claims.
