Celtic Fissure

The Fissure is one of three natural boundaries that separate Mountains of Rain and Night from the outside world, the other being the mountains around Three Step Pass and the Breach. The Fissure is large split in the earth that runs out into the sea, separating the Mountains of Rain and Night from Celtica.

During Darkness's invasion of Celtica during the Second Magican Civil War in The Burning Bridge, she constructed a bridge that would carry a large number of her Black Army across the Fissure. These warriors would sweep around to attack the Allied army on the Plain of Uthal, coordinating with a frontal assault through Three Step Pass and a number of Skandians attacking through the Fens. However, Callum, Claudia, Rayla, Soren, Yellow, Fireworm and Evanlynn managed to burn this bridge, eliminating the threat.
