History
The nation was founded on the coast of the Sea of Swords, in the year -4974 DR, by a group of dwarves that were believed to have a much larger, more prosperous dwarf kingdom. They were believed to have been armed with a mighty arsenal of magic weapons, granting them strong defense against the goblinoids and leucrottas in the area. Around 300 years later, they completed construction on the fortress of Sonnmorndin on Arauwurbarak island, in the Moonshae Isles.

In the year -3389 DR they sent out a fleet of ships, very few of which returned. It was believed the sea had driven the dwarves mad, and degenerating the realm dwindled over time until it was overrun by the orcs, trolls, ogres and bugbears of the coastlands.

It was believed the survivors of Haunghdannar eventually became the Madbeard berserkers that raided Northlander ships from their island home in the Uttersea.
