"Just my grandfather and I. Well, there is Death of Rats, and Grandfather's butler." She nodded. "There was an accident. Even Grandfather couldn't save my parents because their time had run out. He offered to let them live in his Realm, but they felt they should move on. Oh, and Grandfather has a horse, Binky. I believe he originally got Binky when he first rode with the Four Horsemen. Did you know there were really five horsemen? Nobody ever seems to remember Kaos. Ronny is frequently irritated by that."
Susan nodded again. "In my universe, when people believe in something long enough and hard enough, it becomes personified. That Death. Here, as far as I can tell, people seem to die without anyone being there to show them the way. It must be very disturbing."
"No, I am a professor at the Ankh-Morpork School for Exceptional Children. I only fill in for him when needed, and sometimes help him with other little errands. Its the price I have to pay for being part of the normal world and the supernatural as well."
Susan smiled at the memory of the Doctor. "He seemed a very energetic individual. Ordinarily, I would be able to find anybody who was on Grandfather's list, but as I said, there seems to be a different system here, so I really can't help you with that."
