I'd honestly quite like it if Selenia were to return once at least one of the Xavax's was established, only to then make her home in somewhere like Highmarch where she'd probably be able to argue convincingly that there was no justification for banning her :p
The you could have the two rival Xerarch's of the north and south suddenly dealing with the fact that the "True" Xerarch had returned and wasn't picking either of them :p
