Waluu, also known as Lo'Gosh in orcish or Goldrinn in elven, was a massive Ancient renowned for its ferocity in battle. He resembled a white wolf-beast and was already 10,000 years old when the Burning Legion first invaded Azeroth. The wolf god slaughtered hundreds of demons before he fell in the invasion. He is said to have aided the night elves of Eldre'Thalas in holding their city against the Burning Legion, only to vanish after battle never to be seen again.

His legend extends throughout Azeroth to elves, trolls, goblins, and dwarves — who all have their own version of the story. In each tale, the ancient's unyielding will and sheer ferocity enabled him to push through the boundaries of the afterlife to aid his people
