Tuqahocuilit, the burrowers

The Tuqahocuilit are large, worm-like demons that burrow through the stony, fleshy ground between Hell's many levels. As such they are in a unique position, and are one of the few demon races to move freely between the planes. They hold loyalty to no single demon lord, and often delight in playing them off against each other. They have been known to grant access through their territory for demon and soul alike, but will always exact a heavy toll.
