Arelith

A slaving system similar to one in Aundor as Azuliah mentioned in earlier threads.

A Thayan conclave/embassy similar to one in Cordor for Amn (which also could be used for slaving function)

An area where surface gnolls can live and inhabit, that function similar to the old Stained paws.

We have talked about slavery on the surface, and if it happens, Sibayad is the logical place for it.
