A few days ago I came up with the name Aretisia and I was wanting to use it as the name of a region or the world that Inkagafar takes place on, but the more I think about it the more I want to rename the Inkagafaria region instead. The duplicated name just causes confusion (there is an in universe explanation though) and Inkagafar/Inkagafaria are the only remaining major names that have stuck since 2012 - I'm tempted to rename the region Aretisia. The town would still be called Inkagafar though.

With the region changing name from Inkagafaria to Aretisia I'd probably change the name of the game too, from Inkagafar: Tenebris Dominus to Tales of Aretisia: Tenebris Dominus. I'm still on the fence though because a lot would need to be rewritten for this to happen.
