Remorhaz

Remorhaz, sometimes known as polar worms, inhabit only chill arctic wastes. They are very aggressive predators that devour any animal matter, including Humans, demi-Humans, and humanoids; they have even been known to attack frost giants.

A remorhaz has a segmented body with a winged head and neck, standing on dozens of chitinous legs. Remorhaz have an ice blue color everywhere except on their backs, where a streak of white sets off the many protrusions located there. They can measure anywhere from 20 up to 40 feet in length, or in rare cases even larger. Their language consists of roaring, bellowing, and howling.

Note: Remorhaz originally appeared in this form in the 2nd Edition Monstrous Manual for the AD&D game from TSR. Their use here is for the purposes of providing context for the campaign only.
