The Icewall Ravine was a ice canyon that was located in the Tomb, an ancient prison on the planet Belsavis. The ravine linked the Ancient Stasis Zone to the east and the Warlord's Deep to the south, and a Rakatan vault was located in the canyon. During the invasion of Belsavis, the Esh-kha species overran the ravine and the vault. After their conquest of the galaxy, the Eternal Empire built a shield bunker in the ravine to support the Star Fortress that was placed in geosynchronous orbit above the Tomb.
