From Halopedia, the Halo wiki
The region houses Iruiru Armory, a weapons manufacturer located in the western tombolo clusters in Iruiru. Iruiru is also home to the most prominent war college on the planet, of which Rtas 'Vadum and Usze 'Taham are alumni of, both having graduated with honors. The college was destroyed sometime between 2553 and 2555 during the ongoing civil war that embroiled Sanghelios.
