Topsy was a deep gnome wererat living in the Underdark with his twin Turvy during the Rage of Demons[as of when?].
The gnome was very close to his twin Turvy. He was the more sociable of the duo. They feared that someone would discover that they were novice wererats who couldn't easily control their instincts.
Topsy and Turvy lived in Blingdenstone. During the Rage of Demons, they were infected with lycanthropy.
Later, during a trip to collect some mushrooms, he and his twin were captured by drow slavers of Velkynvelve.
