Well the rebels will need somewhere to go.
I had a character on Atamara once, for a day in 2007. As far as being a "white knight sheep character" goes, that's a first for me. But hey, if Sayuki is unsatisfied with the way things are going in Xavax, he's free to return to Alara, I'm sure they'll be happy the have him back.
Sayuki will be unhappy wherever he is :p
