Guldat is a dead volcano sited in the southeastern reaches of Borngring. In the Lith-Crillion Era, Guldat served as the home of a large band of fire giants. Back then the volcano was active, but this did not stop the giants from building a basalt and pitchstone castle called Harknori. Over the next one hundred years, it slowly grew to be a castle and walled town with nearly 200 giants.
In the Horgon Era, Guldat's giants came to be led by a charismatic and powerful fire giant named Kelksorli. When Guldat erupted in 110 HE, the eruption provided the "ideal" opportunity for the fire giants to go on a massive offensive against the Volgad. Guldat's eruption resulted in enormous amounts of lava. The flows turned turned into rivers that slowly made their way north. In what became known as the Lava Flood War, the fire giants used these rivers to assault the holdings of the Volgad.
