A juvenile cave worm has left its brood or eaten them, and has started to establish its own territory, hunting in regular intervals. These young worms tend to be more aggressive towards other life forms than their relatively mellow adult kin.


Cave worms are gigantic scavengers who shape their environment as they bore through rock, ice, or other substances on their search for food. These behemoths consume everything in their path. Though they usually prefer soil, minerals, and occasionally constructed buildings, they will also eat living creatures, plants, and other organic materials. There are numerous species of cave worms, each a different color and perfectly adapted to their surrounding environment. Cave worms rarely exceed a typical animal's intelligence. They're also poor parents that lay a clutch of eggs sealed in a protein shell before abandoning them. After a short incubation period, the young hatch, forming a swarming mass of ravenous larval cave worms. When nearing maturity or when starved of sufficiently rich soil, these larval worms turn on one another. They fight for dominance or flee until only a few remain. The survivors grow quickly, rapidly becoming juvenile cave worms.

Brood Variance

The cave worms presented here are typical of standard rock worms. For crimson worms, use the elite adjustment and add immunity to fire. For azure worms, increase their swim Speed to 40. Gray worms gain void healing and a weakness to vitality energy 5. Glacial worms gain immunity to cold.

Early Hatchling

A single cave worm egg can produce several thousand larval cave worms when it slowly matures over a millennia. However, if a cave worm egg is disturbed or damaged before its natural cycle completes, the egg enters a rapid stage of maturation. Only a few hundred worms survive this process, creating significantly fewer offspring than when allowed to mature slowly.
