Dr. Zed grew up in Utah, in the more rural parts. He moved into this area when he was 20, and has lived here ever since. He was a relatively normal man, living as a Professor in the local University. He had a wife and no children. Doing to his wife being very vigilant about stocking up, he has an abundance of supplies, including medical stuff. When the apocalypse began rudely interrupting his life, he converted his basement house(ish-thing..) into a makeshift bunker of a clinic. He rarely gets any patients anymore, as most people are dead or mutated, but he tries to be helpful to passers-by by giving them medical attention, a place to crash a few nights, and pointing them in the right direction.
And yes, hes got a PhD. Hello, "Dr." Zed?
