Dominion of the Dead
Naxt was settled during the Age of Settlement, and unified during The Five Kingdoms period. A stable and prosperous island kingdom for hundreds of years, its history took a sinister turn when Mount Sker erupted at the beginning of the Darkness. The mighty dragon Asestet crawled from the lava and took command of the Armies of Abomination from the foot of the mountain, as the survivors on Naxt became her willing or unwilling servants.
The island collapsed into anarchy after the Syawar defeated Asestet. After two decades Asestet’s son Grond defeated rival warlords and became the (unofficial) King of Naxt. His forty year reign of terror ended when the PCs killed Grond and returned the island to its old lawless state.
