Erebor

Erebor, also called the Kingdom under the Mountain, was founded on the 26th of November, 741 A.T.F. by King Óin II of the House of Durin, and construction on Erebor began the same day. The dwarven city is located in the southernmost mountains of the Golden Hills range on the continent of Syltör.

The Age of Óin
Shortly after the immigration to the region, the dwarves converted to the local religion Tossanism, and their new patron deity became Attinstáinz, the deity of earth and of the forge.

The Kingdom under the Mountain joined the Confederacy of Ryzan briefly after the confederacy's founding, and was dedicated to providing support to all Confederacy of Ryzan member nations.

However, migrants from Tossagrad move into the western part of the region, claiming a single mountain, which was separated from the rest of the chain by the River Running, as the location for their hill fortress. This outraged the Dwarfs, who saw the hills as their exclusive right, and nearly resulted in them declaring war on the Volkorites. However, CanadianToss offered to purchase the land to avoid war, and so they calmed for time.

During the Collapse, the dwarfs decided that they were done with the confederacy, and so, in a move that singlehandedly disproved the dwarfen sayings about honor, oaths, and allies, they abandoned the region, leaving their single hold of Erebor under the trust of GreenToss of Nova Balreska, and zman, the last dwarf of Ryzan, who would turn it into a warehouse. They would then migrate to a land far to the east of their holdings, allowing their sacred hills to be carved up by the newly created Commonwealth of Ryzani Crowns.

State of Khuzdurin
as of January 1, 747 A.T.F. King Óin II proclaimed himself High King of Khuzdurin, with Erebor as the capital state and city.
