Karak Kadrin, known also as Slayers Keep is a Dwarf stronghold which guards a region of mountainous passes known simply as Peak Pass, an important trading route which runs through the Worlds Edge Mountains from the distant east to the Old World. A mighty and well-known kingdom, Karak Kadrin benefits from its position, having become both a wealthy trading center and the largest, most populous and most powerful Dwarf kingdom in the Pass. Peak Pass is also an invasion route for the creatures plaguing the lands to the east, who, unchecked, would be free to rampage into the Old World. Despite being besieged countless times, Karak Kadrin has never fallen. Its impregnability is probably due to the fact it has become the home of the feared Dwarven Slayers, who are naturally attracted to such a contested place. On account of this, Karak Kadrin is commonly known as "Slayer Keep", and is an important centre for the worship of Grimnir, the Dwarf Ancestor God epitomizing fearlessness and fighting spirit.
The Dwarfs and the many outposts they garrison along the route provide welcome security to the caravans in what would otherwise be a dangerous region, as well as keep a vital trade route open. In return, the Dwarfs collect much gold in tolls, paid willingly by merchants.
Following the tradition of his ancestors, Ungrim Ironfist, the king of Karak Kadrin, has taken the Slayer oath himself and must serve both as king of his realm and as a Slayer. However, bound by his duties as a monarch, he cannot leave and seek a honourable death in combat. Therefore he fulfils his Slayer oath by providing for other Slayers as they seek to fulfil their vows. At Karak Kadrin, a weary Slayer may find lodging, food, and hospitality for as long as he needs it before resuming his quest for death. In return, those Slayers who remain at the keep are expected to help the King uphold his pledge to guard Peak Pass.
