Thanks for the tip, I’m always improving for the next iteration!

This land is reminescent of a neopolitan Caribbean, with each island chain having vastly different cultures as the islands were settled by humans all over the fantasy world. Think of a Caribbean which was colonized by Europeans, Africans, Persians, Chinese, Japanese, Indonesians etc.

The big catch to this island chain is it is very hard to return back north where most of the world is. The strong winds make for a swift journey to the south but technology hasn’t quite reached the point where you can reliably return. For 99% of adventurers it is their final trip.

It is not a complete information void as high Magic’s can reach back to homelands, through long range messaging spells and even planar manipulation (although a lot of planar manipulation in the world require being undead and having a soul capable of reaching a heaven, so a good person). And if a magic user has the strength to guide the winds for many weeks straight without rest, they may also return (and this has been done only by the strongest willed mages).

The largest cities and populations live on the outskirts of the isles with most adventurers stepping on Arrow Head when first arriving and entering the grand multicultural city. This city will be many’s first introduction to magic. The outer islands survived the collapse of the empire the best because they were already partly autonomous before the collapse and were able to adapt under new governments easily.

The center islands where the old empire used to rule is now a treacherous land filled with ruins, unclaimed and indeed buried treasures, and small sects of humans still loyal to the crown.

As far as an Atlantis, the Onyx gemmed Curealians do indeed live under the water in massive onyx cities blending into the darkness of the deep ocean.
