Abyss Worm

A frightful relative of the sandworm, this horrific creature can be found on all terrain, its gnashing maw able to bore through solid rock. Thanks to their robust digestive systems, worms display a near-immunity to poison and ability to absorb all manner of typically hazardous substances with no ill effects. Most scholars believe that abyss worms were originally a particularly powerful worm species that further mutated when exposed to magically contaminated food. Tales speak of an expedition investigating mysterious subterranean rumblings coming upon one of these monstrosities in its lair.
