14

Unit 14878836 - Designation: Law Enforcement. Fourteen was an officer of the law, long ago and far away. The memories are faint now. All his memories are faint, at least the ones before the long darkness and The Deal. If he strains, he can recall long stakeouts, rooftop chases, interrogations in dark rooms. Always chasing, always hunting. Never resting. Captures, convictions, commendations. A raging storm. A fleeing form. Leaping from roof to roof. A hand slipping from brickwork. Rushing wind. Falling. Darkness.
A deactivated warforged was brought back to Grashnu by a seeker tasked with hunting a lost amulet, hoping to mitigate his failure. A bizarre curio, it stood in a vault for years, subject to occasional experimentation by alchemists and artificers, until extended fiddling inside its head unexpectedly relit the light in its deep-set eye sockets. Under questioning, it gave a numerical designation and a job. Police Officer. Criminals have no use for a lawman, but the twisted minds that had experimented on the automaton saw an opportunity to answer another question. Do the warforged have souls, or a close enough approximation to be of interest to the unholy beings beyond reality.
Fourteen doesn't know how he was reawakened. How the half-orc and his minions acquired his chassis and restored his consciousness. But he does know how little use men of their kind have for a police officer. The memories are vague again. Someone asking if a warforged has a soul. Grashnu smiling. Chains, a hard floor and strange ritual markings around him. Darkness again, and then a sharp pain inside and a sudden presence alongside his own in his head. A dark voice, whispering dark secrets. An understanding, that Grashnu was his new master. Since then, the memories are clearer. Still hunting. Not only criminals, but artifacts, treasures, anyone or anything he was told. No longer making arrests, but handing out more brutal sentences himself. No more backup from fellow officers, but new powers whispered to him by the strange voice.

Ocassionally hears non descript noises and gutural voices in his head
Over time runic marking appear on his shell growing more numerous and severe over time
Draws unfathomable knowledge from this many eyed void and slowly sends his mind insane
Have a desire to please the great old one, to become powerful enough that he'll notice 14 and include him in his plans
