Kolm is hired, along with Rodrig, to escort the body-stealing mage Fulmin to TzHaar City. He is the son of a blacksmith, and so the dry heat of the volcanic city doesn't bother him. He is the one to locate an inn for the trio to stay in until Fulmin pays them for their protection.
Later he is hired, again with Rodrig, by the TzHaar-Mej to find and retrieve the outcast Ga'al-Rek. They encounter Ga'al-Rek trying to leave the city with Fulmin and are killed in the ensuing fight against the mage.
