Founding
~3200 BFA: The foundation of Krunbar, north of the continent of Rexendell. Initial settlers consisted of twelve Dwarven clans united under the leadership of King Durin the Forgefather. Krunbar prospered due to its lands being inhabitated by vast mountain chains containing mineral deposits and the Dwarves' expert craftsmanship. The capital city of Khaz Morgrum is established around the same time, beneath what is now known as the Frostfang Peaks. Over the next several hundred years, the city would expand and delve deeper.
~2900 BFA: The Great Forge of Krunbar was built, a marvel of Dwarven engineering that allowed them to craft goods of unrivaled quality. The location of the Forge has since been lost.
1176 BFA: The Dwarves, in a bid to explore deeper into the earth, discovered the Underdark, another realm which borders the material plane, unintentionally making first contact with the Drow. The incident became known as the Dark Discovery.
The War of Shadows

The last king of Krunbar transfers his dying soul to a Warforged body in hopes of survival, but as with all souls that inhabit Warforged, the identity is lost.
