This plan was, of course, decided after first discussing it with the various dwarven Gods.
Though he might have spared those lower-ranking Isis members from execution, Sui Xiong couldn't just let them go without any punishment at all. According to tradition, if someone was spared from execution, they should usually get a hard beating, followed by exile. He didn't feel like beating them up though, so he just went with exile.
But where they should be exiled to, was a big problem in itself.
He couldn't throw them into one of those places where only tenacious creatures like cacti could survive, nor could he send them to a dangerous place where demon beasts ran wild. These didn't conform to the idea of "sparing them from capital punishment." Plus, if these people weren't looked after, who knew what sort of trouble they would get up to!
