ok so i was thinking that on the arcane planet you would have to major cities, and two waring factions. both are seeking immortality and eternal youth but they are going about it in different ways. so when you come to this planet you have to choose a faction. one is fighting for Grigori and against Hurbert East, the other is fighting for Hurbert east and against Grigori. one of the final missions would be to fight the leader of the opposing side.
