Despite what many seem to think I'd consider the current war to be quite an large dynamics changer for Atamara. Much like when RedSpan/Abington fell. The Cagilan Empire/Tara/friends lost the enemy they had fought against for the past half a decade or something and that meant them finding new targets.
I don't think the Cagilan Empire will be the same after this and thus there will be change in the island. How much difference there will be depends on the resolve of the realms fighting against them.
