Kadrin Valley A lush valley surrounded by towering peaks, Kadrin Valley is a land of contrast. Many travelers are surprised by the transformation of the chill mountain trails into verdant valley roads. Home to the Dwarf Slayer Keep, Karak Kadrin, Kadrin Valley guards both the route to the Dwarf capital, Karaz-a-Karak, as well as several passes to the Empire. Like the Dwarfs of Black Fire Pass, the Slayers of Kadrin Valley must hold these passages, lest they betray the Dwarf allegiance with the men of the Empire.
