The Worm represented the twelve millennia-old vestiges of a dead space worm. This creature had once lived on the moon Eskaron, and its remains composed the tunnel walls where it had made its final resting place. Sometime between 72 BBY and 53 BBY, its discovery occurred during a race through the moon's depths. A racer named Likk Nibk inadvertently found it while attempting to overtake a competitor piloting a YT-1300, taking an incorrect turn. Nibk's ship burst through the worm's end, ultimately securing his victory in the race. Subsequently, researchers investigated the site, and race routes were diverted to avoid the worm's location.
