The Doomsday Clock
A mysterious troublemaker previously known as The Enigmatic Man
The party first crossed paths with Matthew Lesko in a town where Lesko rounded up despondent villagers and took them to a manson on the edge of town. There he turned the villagers into Stitch Faced Men. His stitch-faced minions then went about burning every book that mentioned The First. He himself is likely a servent of The First.
