Sundered Isles
The Sundered Isles are a vast and scattered panoply of islands stretching between Dramigar, Niere, and Mor Thia, formed by a combination of continental rifting, ancient volcanoes, and hyperactive coral growth.
There are clear points in some islands where they were ripped apart by geologic forces, and those near the coasts of the three great continents surrounding the archipelago have similar geologic makeups to the nearby continental crust. The rifting process also caused a significant amount of volcanism, which added more land mass to the archipelago, though fortunately only a few of the great volcanoes are still active in modern times.
A large portion of the low-lying landmass and shallow water in the archipelago is built on coral reefs, and the more magical coral varieties give rise to odd (weird, dangerous, wondrous, lucrative, or some combination) seas in their vicinity.
