Before she was banished to Dimension Y, Vera was the leader of the League of Chaos, which was an extremist group of all the town’s villains. In her last clash with the Master Alchemist, he was able to open a portal that banished her to Dimension Y, a remote wasteland. Vowing revenge for her banishment, she has found a way to return to town.
