MERP Isengard and Northern Gondor I.C.E. 2800 Middle-Earth Role Playing 1st Ed 1983
Isengard and Northern Gondor The citadel of Isengard was built by the Númenórians in a sheltered valley at the southern limits of the Misty Mountains. Its main purpose was to defend the gap of Calenardhon and the Fords of Isen against attacks by Sauron's forces.
Self-sufficient and enchanted, it later became the virtually impregnable fortress of Saruman the White. No spire in Middle-earth was stronger, save the Dark Tower of Mordor.
