The Icewall Ravine, a frozen canyon, existed within the Tomb, an age-old prison situated on the planet of Belsavis. Functioning as a connector, the ravine provided passage between the Ancient Stasis Zone to its east and Warlord's Deep to its south; furthermore, a Rakatan vault was present within the canyon's confines. In the course of the invasion of Belsavis, the Esh-kha species seized control of both the ravine and the vault. Following their conquest of the galaxy, the Eternal Empire constructed a shield bunker within the ravine, designed to bolster the Star Fortress positioned in geosynchronous orbit over the Tomb.
Within the video game Star Wars: The Old Republic, the Icewall Ravine is depicted as a distinct subregion of the Tomb on Belsavis. The 2015 Digital Expansion titled Star Wars: The Old Republic: Knights of the Fallen Empire introduced the Zakuul shield bunker to the canyon's landscape.
