Aurium Labs.
A discreet lab known for their epidemiology studies. At least, on the surface. Their real research lies severely deep under the surface, the underground lab. Creation of half-human hybrids, experiments on humans, research on forbidden topics, all could be considered blasphemous. The Head Scientist, Dr. Beaumont, a polite and respected man on the outside, yet cruel and unfeeling underground.
One of the lab's most successful creation was a half-demon hybrid child. This child was originally from a regular suburban middlr-class household. One unfortunate day, strongman of the underground lab kidnapped him. He remembers the day vaguely, his memories mostly erased.
The boy despised the bright sterile surroundings. That portrait of Beaumont.. It fills him with disgust to this very day.
To him, the days of his pitiful existence went by swiftly. Same white cells and corridors. The coldness of the labs, and the scientists. Occasionally taken out for check ups and tests.
Being combined with Demonic Essenves meant that he officially became a blank slate, devoid of past: Test Subject 656.
