The Breaking of Carth
A large heavily volcanic island mostly inhabited by Dragonborn and Goliath, with the former making up a ruling class and latter a subservient one. Before the rise of Carth, both races had served the Draconic Empire which had ruled the majority of the southern archipelago for a thousand years. The Dragons created both races, the first in their own image, the second from the very bedrock of their volcanic home.
Kisp has recently been the site of a catastrophic event dubbed The Breaking in which an enormous comet-like object wreathed in purple flame crashed down into Drogash, the enormous sporadically active volcano at the centre of the island. No clear reports have emerged of what exactly happened, but Kisp appears to have been split into several pieces with lava flowing freely right to the sea, and rumours from the island are always consistent in mentioning elemental beasts of all shapes and sizes sowing destruction.
