Rulkan

Rulkan was the mate of Ner'zhul who died more than 9 years prior to Draenor's discovery by the Burning Legion.

In life, she had never held a position of authority. As a spirit, she had occasionally visited Ner'zhul in visions to provide him with comfort.

Kil'jaeden impersonated Rulkan's spirit and told Ner'zhul about the false draenei threat. After talking himself up as a benevolent spirit who would help the orcs, Kil'jaeden eventually stopped using Rulkan's visage and appeared to Ner'zhul as himself.

Some time later, Ner'zhul's doubts about Kil'jaeden compelled him to seek out the ancestors in Oshu'gun for guidance. He was met by the real Rulkan who looked upon him with hatred and told him that there was nothing he could do to redeem his betrayal of the orcs. Rulkan and the other spirits turned their backs on Ner'zhul.

Upon his defeat in the Maw, the last Remnant of Ner'zhul addressed Rulkan's spirit, announcing that he could now come "home", thus finding peace and presumably reuniting with her.
