Nullipede

A nullipede is a fearsome snakelike creature large enough to swallow a man whole. SX3 encounters a fully-grown nullipede on the airless clan-hold of Graviticus and Photicles. While the beast's tough carapace reflects burner charges, SX3 manages to trick it into biting the drill of the commandeered MDP.

The Apprentice encounters a nullipede while wandering in the vaults of the Empire of the Dragon. She identifies this creature as a rock-worm.
