The Worm

The Worm was the 12,000 year old remnants of a deceased space worm on Eskaron. It formed the walls of the tunnel it was in when it died. It was discovered during one of the races through the moon's interior, when one of the racers, Likk Nibk, took a wrong turn. He blasted through the end of the worm and ended up winning the race. After that, races were routed away from the worm's location.
