Alastor

Death in Red

Orphaned at a young age during a border skirmish between Imperial forces and a rebellious Chimera clan, he was taken in by a strict order of warrior priests dedicated to the Emperor Eternal. Within the monastery's walls, he was taught that the only true path to salvation lay in unwavering service to the Empire. The priests, recognising his potential even at this young age, cultivated his hatred for Chimera and other “outsiders” and praised it as holy virtue.
He excelled in the martial disciplines, his rage and pain fueling many sleepless days and nights of relentless training. As he aged his fanatism only grew, until even the priests began to find him dangerous to interact with. He would lecture his elders for the slightest indiscretion, for violating rules so minor that most had long forgotten them. When he reached maturity the elders told him of a vision they'd been given by the Emperor himself, one of Alastor venturing to the Arbiter Academy in Aetheris where he would find his destiny.
At the Academy, he distinguished himself through sheer ruthlessness and an unyielding commitment to completing any task, no matter how brutal or morally questionable, with chilling efficiency. He had no interest in the complexities of law or the subtleties of interrogation. He saw the world in stark black and white – the Empire and its enemies.
Upon graduating, Alastor rose through the ranks with terrifying speed, leaving a trail of blood and broken bodies in his wake. He garnered a reputation amongst both criminals and his fellow Arbiters – a man to be feared, a tool best kept at a distance unless absolutely necessary.
