Karak Kadrin

Karak Kadrin, which means "Hold of the Mountain Pass" in Dwarvish, 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 Southern Reaches. 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 Human lands to the South. 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 Dwarfen 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 the Dwarven god Dumathoin, patron of the Dwarves.
Karak Kadrin is ruled by a single mighty King, who is normally chosen from the strongest of the Slayer caste within the Karak. Karak Kadrin is well known for it's martial standing Amongst the Karak's and has the best relations with the Human Kingdoms to the South, though they still prefer to be isolated from them when possible.
