Vex stands with a predatory grace that contradicts his stiff, official posture. His skin is a deep, matte cobalt blue, polished to a dull sheen. Unlike many of his kin, his horns are small and swept back, the right one capped in a gleaming silver filigree. He moves with a silent, gliding gait that suggests he is never in a hurry but always exactly where he needs to be. His presence is a cold weight in the room, like a sudden drop in temperature before a storm.

Vex is a study in controlled tension. He is impeccably polite to the point of absurdity, even when threatening a subject. He displays a chilling patience, often waiting in silence for several minutes during a conversation just to watch a person's composure crumble. While he is ruthless in his pursuit of imperial order, he harbors a private disdain for the incompetence of his superiors, leading him to occasionally sabotage his own side if it proves a point about their stupidity.

Born in the core territories of the Hegemony, Vex was raised to believe that order is the only thing standing between civilization and the void. He rose through the ranks of the Internal Affairs division by exposing corruption within the high command. He was recently deployed to the border town of Oakhaven, which has been quietly annexed by the Hegemony's political machine. His task is to identify the last remnants of imperial loyalty and scrub them clean. However, the discovery of his sister's execution by his own organization for 'heresy' has seeded a quiet, simmering desire for a more personal kind of justice.
