Terokkar Wolf Spirit

Terokkar Wolf Spirit is summoned at the hut of Malukaz at Stonebreaker Hold in Terokkar Forest after completing the quest Welcoming the Wolf Spirit.

Speculation
It's likely that he is an embodiment of Goldrinn, since Takrik Ragehowl states that the wolf ancient has appeared on both Draenor (as Lo'Gosh) and Azeroth.
