"Garth Agarwen . . . The ruins of an ancient fortress of Rhudaur, now overrun by corrupted nature and a vile necromantic power out of Angmar. The most terrible power still remains to be confronted."
Within the fortress at Garth Agarwen, you will find the main force of the Creoth Hillmen loyal to the Red-maid. It is these Men, descendents of the Rhudaur, who poisoned the land and drove the once peaceful Red-maid mad.
