Icetrompers were enormous beings who made their home in the valleys nestled among the mountains of the icy, snow-laden Outer Rim planet of Gigor. These valleys, where hardy shrubs, mosses, and coniferous trees thrived, formed the environment that sustained the icetrompers, along with fellow inhabitants like ice scrabblers and jakobeasts.
Within the existing Star Wars canon, the initial reference to icetrompers occurred in Dawn of Rebellion, a 2018 addition to the Star Wars Roleplaying game system, which was created by Fantasy Flight Games. These creatures initially existed within the Star Wars Legends storyline, making their debut in the 2011 massively multiplayer online roleplaying game titled Star Wars: The Old Republic.
