Isharg was a dwarven clan that arose in the kingdom of Gimhak. It formed from two other clans that were joined in marriage. Five years after the clan took its name, and said to be politically motivated, they were selected by lottery to be colonists. In 1415 HE, they set-off southeast and six months later founded the settlement Anarukthalan.
In 1255, the Orchish Empire besieged Anarukthalan. After the city was reduced to ruin, the Isharg were rounded up and put to the sword. This was ordered by the High Command in retaliation for similar genocidal deeds carried out on the orders of their foes.
