Karontor is a wicked, misshapen Power whose hatred of giantkind reflects his own deep self-loathing. He associates with the equally wicked and warped fomorian giants, but evil verbeeg also carry his mark and prove superior spellcasting servants, given their higher mental capacity. Karontor dwells in a mausoleum of beast and giantish bones in a desolate, frozen, wind-swept plain of Tarterus where his pack of ever-hungry winter wolves awaits his signal to rage across the miles beyond. Here he grows ever more embittered by his banishment by Annam, which stripped him of his own spellcasting powers. Annam did not truly detest Karontor, he simply grew weary of endless sibling fights and dispatched Karontor because it was the easiest thing to do; thus, this evil Power's grievance has some justification.

Karontor's vicious clerics are urged to fight all good creatures, using trained beasts (especially wolves) for this purpose. They constantly urge their own groups to conflict and war.
