Julien stands a little over six feet tall, fair of skin, grey of eye, and black of hair - apparently. His eyebrows are drawn on and his short black hair is in fact a wig. His lips and fingers bear the signs of an often-indulged lho habit. He has the detached, appraising gaze of a man who has seen some of the worst that humanity has to offer.
A Sinopian, Julien grew up as a junior scion in a minor trading house. He was driven to find success and found that fate favoured him. At least as much as it favours anyone it deems unworthy enough to be born on that slowly-rotting world.
The reason for that luck is what got Julien kidnapped on a rainy night by a canal, walking back from a taphouse.
He disappeared for three months and was given up for dead. Then the bedraggled Julien was fished out of the same canal, with no memory since he had felt himself lose consciousness.
His luck then completely ran out: a black ship of the Adeptus Astra Telepathica was in orbit that very day. Their auspexes determined that Julien was in fact demonstrating minor but significant psychic potential. He was taken to Holy Terra and a measure of his good fortune returned to him.
Julien was tested and found not wanting.
That said, Julien's testers found that while they could determine the strength of the testee's mind and his psychic potential, they could not *read* it. It was determined that to make best use of this anomaly, the newly trained psyker would be assigned to Inquisitorial service, back in the Calixis Sector where he was originally found.
