Siremun was the last Dwarven kingdom to be founded in the Dwarven expansion at the height of their races power during the Age of the Proud Peoples. The Firepeaks were discovered by a band of dwarven adventurers in -11900 DR who then decided to settle there as many of their kin had done. The last wave of the dwarven expansion followed them after many years. Unfortunately, no more dwarves followed them that far and eventually communications completely broke down with the west.
