Name: Finn
Title: No official title
Nicknames: None known
Martial Status: Single
Major Accomplishments:

• Finn is a young woman from the future. In her future, the world is destroyed by a nuclear holocaust brought about by a demon named Zoth. Only the Plateau was able to survive, but it turned into a wasteland run by oil mongers. Finn meets Challenger, Marguerite, and Roxton when Challenger’s transportation device mistakenly sends them into the future. She returns with them.
• Her encounter with the demon Kayle, who is the same person she recognizes as Zoth, alerts the Challenger Expedition to another reason they need to get off the Plateau. They now have to warn the world of what catastrophe awaits it in the future, hopefully preventing it from happening.
• Had the same stuffed lion when she was a child that Veronica has during her youth. Is it just a chance happening? Or is there a connection?
