Shattered Teeth

The Shattered Teeth is a major archipelago of 43 islands located on Exandria, southeast of Tal'Dorei and far south of Wildemount, past the persistent fogbank known as the Fool's Curtain. Varying in size from mile-wide reef-top isles to large, city-holding islands like Ruukva, this archipelago is mainly split between two conflicting societies: the Ossended Host and the Wanderman Assembly.

Geography
A paper map shown on-screen places an outline of the Shattered Teeth at a lower latitude than southern Marquet, but a later official map by Andy Law shows the Shattered Teeth in a different shape, at the same latitude as northern Marquet.

The Ossended Host
The Ossended Host are a huge society of isolationist fishing folks who seek enlightenment via the worship of dreams and nightmares.

The Wanderman Assembly
The Wanderman Assembly is a ruthlessly capitalistic society that claims to hold to the virtues of honor and brotherhood. It was originally a trading company from the Menagerie Coast that wrecked in the Shattered Teeth due to a hurricane.

History
Prior to the Calamity, the Shattered Teeth was a continent known as Domunas. The fall of Avalir and the energy released in sending the primordials Rau'shan and Ka'Mort to another plane destroyed it, leaving only the island chain.

In the years shortly before 812 PD, the tension between the Ossended Host and the Wanderman Assembly had become somewhat violent. A deeper element of the conflict is the source of the dreams on which the Ossended Host has been drawing for centuries.

In late 835 PD, the pirate Sorris Cade told Avantika about a recent return from the Shattered Teeth, which he described as terribly cold and foggy.

There are hard-to-corroborate stories and myths that dinosaurs like the deinonychus, which are said to have existed in the time of the Primordial Titans, may still survive in the Shattered Teeth. (Many creatures from far and wide, including deinonychus and Tyrannosaurus rex, were displaced to Rumblecusp due to Vokodo.)

Source of name
Asmodeus told Zerxus Ilerez that "on the face of Exandria, Domunas was the smile." After Asmodeus was released and began to attack the mortals of Exandria, he said that he would shatter the teeth of that smile.
