Iron Canyon

During the Core War, a battle was fought in Iron Canyon in which several members of the Glatorian species fought, including Ackar. Due to dangerous terrain and narrow passageways, armies were forced to hide often, and march single file. During these single file marches, many successful ambushes were sprung on enemy armies.

After The Shattering, the Iron Canyon region was separated along with other geological locations from Spherus Magna onto Bara Magna. Following that event, the Fire Tribe had established themselves in the village of Vulcanus, located to the west of the canyon.

A few weeks after the Battle of Atero, a group of Bone Hunters led by Fero had rode through Iron Canyon to Raid Vulcanus. However, when the Fire Tribe Agori and a group of Glatorian launched traps in the canyon, the Bone Hunters retreated. Once the Vulcanus forces were convinced the Bone Hunters had given up, Fero's forces rode away from Iron Canyon and instead attacked from the south.

Sometime after Teridax's death, Karzahni escaped the Matoran Universe, but was stabbed by someone, fell into the canyon, and died.
