Fenris Wolfbrother

Fenris Wolfbrother (also known as Fenris the Hunter) was chieftain of the Thunderlord clan, and leader of the few remaining wolfriders in Draenor.

The Blackrock clan had once been very closely tied to the Thunderlords, and Orgrim Doomhammer had risen to power through that clan. When Ner'zhul chose to reforge the Horde after Doomhammer's defeat on Azeroth, Fenris pledged his Thunderlords to the cause.

Fenris accompanied Tagar Spinebreaker on a swift mission to the Tomb of Sargeras, where they slew a demon and claimed the Jeweled Scepter of Sargeras. Fenris gave the scepter to Ner'zhul and fell back into line fighting for the reforged Horde.

Inspiration
Fenrir is the name for the fearsome giant wolf of Norse mythology, fated to break free from his chains on the coming of Ragnarok and eat Odin.

In the novel Beyond the Dark Portal, Fenris' given name is "Wolfbrother". Another Wolfbrother, Garm, was the last of the Thunderlord chieftains, and is thus presumed as Fenris' successor. It's possible that Fenris and Garm were father and son, or brothers.
