Dr Carson Keller was always an eccentric man. He lived most of his life with a sizeable inheritance from the his parents, who died shorty after he born. Nevertheless, he devoted himself to the then dying practice of medicine, becoming a doctor when there no longer any need for people to remain in a dying body. He can remember most of his medical training, but events leading up until the Fall are spotty at best. His last, clearest memory was of splitting his ego into a backup morph some 4 months prior to the Fall, then waking up in a warehouse on Mars next to an empty, badly damaged morph. Records show a 3 year gap he has no memory of between re-instantiation from earth and the warehouse; years he intends to get back.
