A group of Wampas made their home on the planet Hoth, approximately three years following the Battle of Yavin. Before the Battle of Hoth occurred, this group resided in the location that would later become the Rebel Alliance's Echo Base. Once rebel forces forced the group to relocate, the group's leader retaliated against the rebellion by ambushing Luke Skywalker along with his Tauntaun. Skywalker severed the leader's arm, but the leader recuperated and started to adapt in the days that followed, eventually returning to Echo Base and retaking the empty caverns after the Battle of Hoth. Having regained his home, the wampa planned to gather his group together again.
