Cain looked at the outside of the mansion, than at the letter he had in his hand. "Room 23? No idea where that is. But I guess i'm in the right place". 

Picking up his duffel bag, which contained his only possession. He slung it over his shoulder and headed into the mansion. It was big on the inside a lot bigger than on looking at it from the outside.

"Some real time lord stuff going on here". He muttered to himself. 

Finding his room after a lot of trial and error he dumped his stuff in the room. After grabbing a snack to stem his cravings he left the confides of his room to explore the mansion and the ground.
