Ancient world geography and points of interest

[Iscah]

I want to say it's about when we learn about Kitis or are about to enter it. That the inside of Kitis isn't the only place like it where there's a sort of Tardis type thing going on where it's much bigger on the inside.

I've just been through those quests on an alt, and it's the document archives that are "magically bigger on the inside" like Ktisis. No mention of Elpis as a whole being in a pocket dimension.
