The Allagan Empire will likely play a major part in the future; especially since it's directly tied to the Garleans. Quite a lot of people like exploring Allagan related stuff and so I hope we get to see a lot more of it in the future - alongside other 'lost' civilisations.

Going back to Gaelicats, though, I wonder if they're similar to Cait Sith in that they were created as some sort of familiar or pet? One that - like those frogs in Dravania - ended up becoming wild after their masters perished/vanished?
