Thorek's anvil-headed hammer is a formidable weapon of war as well as a useful tool. In his position as Master of the Weaponsmiths of Karak Azul, he has access to a vast amount of ancient rune lore. From his researches and experiments, he has designed a new rune which he has struck onto his hammer. This rune is unique to Thorek's hammer, Klad Brakak, as he only made it a couple of centuries ago and wants to give it a fair trial before using it again.
