Ironhoof

Ironhoof is an aged tauren warrior that longs to prove he is still strong and an asset to both the tauren people and the Horde. He joined Malgar in defending a small orc pig farm laid waste by a band of raiding Kolkar clan centaurs. They succeeded in defending the farm – but Malgar was injured so Ironhoof took him to The Wyvern's Tail in Orgrimmar to recuperate. While the orc was sleeping, the tauren bought him a bow as Malgar's gun was lost in the battle. He offered him to join the Garad'kra, despite the orc wanting to leave the city. Malgar thanked him for rescuing his life and giving him the tauren bow but left with words of blood debt.

Reuniting with the shaman Shagara in the Valley of Honor, she offered him to serve as the stone guard of her and the other members of the Garad'kra. He then watched the duel between Shagara and welcomed Felgrim.
