Gimhak was a dwarven kingdom that reigned in the highlands of Bileddanul for twelve centuries. They were economically strong and helped control some of the evil menacing the central areas of the region Grashakh. As the population and might of the kingdom grew, Gimhak sent colonists to other areas of Brucrumus.
The Ishargs were the first group to leave Gimhak. They travelled southeast into the deep forests of Thithanorn. In 502 they founded the settlement Anarukthalan.
Gimhak architecture goes back to the time when the land was beset by demon hordes. Of military purpose, ceiling height of structures were made suitable for Bileddanul's defenders, mostly Turkûn-Khâl serving under Naraz-Nâru; while impairing the movement of those larger than them. This architecture is a stark contrast to what is seen today in the Clans region. There the dwarven holds have ceilings heights often two to three times what is found in Gimhak's ruins.
