Facts-
While working as a scientist at a facility a fellow lab worker ended up dropping a potion that shadered kill the lab worker instantly, some how shadow survived this encounter with the markings he's has now and suffered from a blindeg of one eye.

He suffers from PTSD from the insdent but still works as lead scientists at the facility, though when sage and tiger where 5 there mother disapered and he went into debt so he gave the girls to some fellow lab workers and left- they found him not a mile away, dead by frostbite and the markings gone (no one knows what happened though >:3)
