Durlag's Tower
From ALFA
This massive, isolated keep stands atop a rock pinnacle south of the Wood of Sharp Teeth. Only adventurers should approach this seemingly deserted fortress, death awaits within. The tower was built by Durlag Trollkiller, son of Bolhur “Thunderaxe” the Clanless. Durlag was a great hero of the dwarves, an adventurer who slew several dragons single-handedly and over a long and successful career amassed a great hoard of treasure.
