Time of event: Just after the Cataclysm
Important characters or races involved: Fistandantilus, his champion, his white robe, and the gnome
Story: The same thing as Raistlin's but he was stopped by the gnome, Gnimsh, and took the cleric Denubus instead of Crysania (and I don't think he was trying to get with Denubus).
Outcome: He didn't become god, because Gnimsh activated the time traveling device and threw the magical field off.
