since Rober has some of imperator's splitting power, he's able to cause amnesia in others like what imperator did to itself and offered to carty. Phrolober's desire "to find a different way" could mean forgetting about the village so it doesn't hurt her anymore. there's some spicy character development.
other possibilities are antagonist roles like chasing more macguffins in lahai-roi or a yandere twist where killing Rober will send him to the Beyond
