Lying at the southern spur of the Misty Mountains, Isengard commands a position of great strategic importance, for to its south lies the Gap of Rohan, the only reliable passage from one side of the mountain range to the other. Isengard itself is a fortress of carefully crafted stone, built in the earliest years of Gondor's existence. At its centre stands the tower of Orthanc, a massive edifice of polished black stone, bound tight with sufficient magic to render it virtually indestructible to physical assault. Though originally constructed as part of Gondor's western defences, Isengard is little mentioned in the histories, which would suggest it remained empty for much of the time.
The first notable resident of Isengard was the Wizard Saruman the White. Doubtless, the kings of Rohan welcomed this, for they were often embattled and in Saruman they had a powerful ally. Though initially Saruman doubtless comported himself merely as a lieutenant in the service of Gondor, he soon became a power in his own right and threw off any pretence at subservience.
Over the following centuries, the White Wizard's thoughts turned more and more to possession of the One Ring. He began to add to Isengard's defences, recruiting to him an army of all manner of unruly creatures: wild Men, Orcs, Uruk-hai, Warg Riders and Goblins. The caverns below Orthanc given over to the smithying of weapons and armour, the trees upon the mountainside felled and burnt to feed the furnaces of Saruman's army. It was in this way that the fortress of Isengard became a threat ever-present upon Rohan's northern border.
