Space Wolves Thunderwolf Cavalry

From the Mountains of the Maelstrom come the legendary Thunderwolves, hulking beasts with jaws so strong they can chew through steel. There are several known instances of senior Space Wolves tracking down and ‘breaking in’ Thunderwolves, and this practice, thought to be an initiation ritual into the upper echelons of the Wolf Guard, has given rise to the near-mythical Thunderwolf Cavalry - a small but dauntless elite within the ranks of the Wolf Guard who remain absent from any official Imperial records.
