Doctor Rogers was a amiable Warforged from New Newfoundland Land. He would just wander around town, singing to himself about being your friend. He was friends with a small train, Trolley (later changed to Charlie), being ridden by a puppet, Wacko. They ride around Rogers' house, delivering messages and being helpful, though Rogers was unsure of where they led.
A member of The Baby-sitters Club, he attempted to stop Mendelov's Marvelous Rainbow Tavern Company from corrupting the town, but failed. As a result, the Company, actually a team of Dragonborn, completed a ritual to bring Tiamat into the world. He was likely killed when this happened.
