Main characters (needs expansion)Edit
Jason comes back to Lyrian after being swallowed by a Hippo (again). Rachel finds that she is talented in Edomic. The two find Galloran, plotting a Rebellion. They propose the idea to the Amar Kabal, who first need proof the revolt will overthrow Maldor. For this, the group must consult the Prophetess at Mianamon. She sees that the Revolt will succeed, but two quests must also succeed for the revolt to have the optimal ending...
