Isharg was a dwarven clan that arose in Gimhak. It was a division from two other clan which divided from an inter-clan marriage. Five years after they formed, and said to be politically motivated, they were selected by lottery to be colonists. In 502, they set-off southeast and six months later founded the settlement Anarukthalan.

In 1255, the Orchish Empire invaded lands claimed by the city-state Anarukthalan. All those of or related to the Isharg clan were put to the sword. This was ordered by the High Command in retaliation to similar genocidal measures being done by certain groups of Gimhak.
