The icewolf originated from the world of Spintir, a planet. These predatory creatures, armed with sharp teeth and claws for hunting, made their home in the forested valleys and mountain caverns of Spintir. Their method involved subduing prey before entombing it in ice. Near the Caves of Light and Shadow, the icewolves experienced a corruption stemming from the dark side, which drove them to madness while simultaneously enhancing their strength and durability. Consequently, other animals avoided the forests surrounding these caves.
During 0 ABY, a group of icewolves fell under the influence of Malefax's presence at the Dawn Temple. This corruption led them to assault a party attempting to rescue Hethan Romund. Subsequently, that same group faced the icewolf pack, headed by a den mother, at the Cave of Light and Shadows, a vergence point in the Force.
The icewolves of Spintir are featured in Star Wars: Force and Destiny, a roleplaying game from Fantasy Flight Games. Players have the option to engage in combat with these packs using different strategies.
