Lord of Isengard

Lord of Isengard was the title born by the master of Isengard, a Gondorian chieftain in command of the local garrison. The guardians with time became secretive and mingled with the Dunlendings until the Gondorian line failed.

Saruman later declared himself as Lord of Isengard, when he was granted to settle in Orthanc. Following the death Steward Turgon, the Wizard no longer paid heed to Gondor and made Isengard into his fortress, eventually abandoning his mission to fall into mimicry of the Enemy as his duplicitous vassal, weaving plots to suit his own personal ambitions.
