Kalmor was one of the Ancients; the first generation of nephalem in Sanctuary. As their powers were diminished due to Inarius's tampering with the Worldstone, he watched on with disgust as subsequent generations of nephalem became mortal and weaker. He considered killing these humans a mercy, but despite possessing the same loathing for himself, could not bring himself to end his own life. He decided that he had to seek another to end his life for him.
