Like an albino earthworm in nightmare proportions, this chitinous beast slides across the snow-covered rocks, the whirling plates in its maw questing for nutrition in the stark terrain.

Special Abilities
Salt Spray (Ex) Once per hour an ice worm can spray a highly corrosive salt solution, similar but more concentrated than its saliva, from its rear end. In addition to damage as listed, the area where it sprays, if ice- or snow-based, is treated as the spell acid pit, cast at the 8th caster level; when the listed duration expires, the acid freezes to a non-harmful form, but the “pit” remains.

Occupying a specific niche of arctic climates, ice worms resemble subterranean purple worms to a certain degree, except that their mouths are far too small to swallow creatures larger than Tiny. Ice worms process tons of ice and snow in their movements, sifting organic particles for food, but are not averse to tasty flesh, should they come across it. They inhabit low foothills in arctic climes, between the mountains and the sea- they assiduously avoid the territories of frost worms, remorhaz, and white dragons, all of which will gladly feast on ice worms. At the same time each year, ice worms make a migration to the sea, to breed and process tons of seawater; their larvae spend a year as mollusk-like sea creatures, then come ashore to climb to their racial territory- and are said to be delicious. Even adults make good eating, if you know how to process the extremely salty meat (DC 21 Knowledge [arcana]). A concentration of ice worms can create a great deal of difficult terrain in an area, “worm sign” of the presence of the beasts.

Ice worms are native to the west coast of The Frozen North, and a warrior that can slay one and bring the carcass to his village will be hailed as a hero for some time to come; ith’n ya’roo especially prize the meat. There are rumors of specimens being seen in The Northlands, but they might just be sightings of their natural predators, the remorhaz and the frost worms. The yearly migration of ice worms is a feasting opportunity for both species, but the majority of the icy snow-chewers make it through to create another generation.
