Yukha is an orc shaman of the Earthen Ring, and a trusted friend of Thrall. He personally came to Orgrimmar to inform Thrall that something was terribly wrong in the spirit world, noting that he had never seen the spirits act as they've done. In light of both the Earthen Ring shaman and the Cenarion Circle druids sensing the disturbance, Yukha agreed to serve as Thrall's messenger to the night elves, who had relocated to Nordrassil. Though Tyrande's rage had not lessened, she did agree on the meeting with the condition that Yukha inform Thrall that he "must bring what is owed." A declaration that confused both orcs.
When Thrall mentioned his intention to bring Baine Bloodhoof and Calia Menethil with him to the meeting, Yukha grew concerned, believing that their presence would remind Tyrande of Sylvanas Windrunner, albeit in different ways. Thrall then cited that Baine despised Sylvanas, and how Calia wished to bridge the divide between the Forsaken and the kaldorei that were raised into undeath as reasons in order to ease his worries. In response, Yukha told Thrall that he felt that it was best if Thrall came alone but acquiesced to Thrall's wishes.
He then accompanied the three to Nordrassil, where in light of the frosty frigid reception they had received and Tyrande's rage, Yukha declared that it was a mistake to bring the Horde here. He then corralled Baine and Calia out of the area and attempted to do so with Thrall. However, Thrall refused to be corralled out and promised Tyrande that he would deliver what is owed, that he would give her the head of Sylvanas Windrunner. The group subsequently departed from Nordrassil.
While the Thrall, Baine, and Calia returned to Orgrimmar, it is presumed that Yukha returned to the Maelstrom.
