An immense centipede-like beast erupts from the snow, rows of chitinous plates on its back glowing red-hot.

From beneath the snow and ice bursts a remorhaz in a cloud of steam, its body pulsing with internal fire. Wing like fins flare from the back of the creature's head, and its wide mouth brims with jagged teeth.

Arctic Predators

Remorhazes live in arctic climes, preying on elk, polar bears, and other creatures sharing their territory. They can't tolerate warm weather, having adapted to the cold by generating a furnace-like heat within their bodies. When hunting, a remorhaz burrows deep below the snow and ice and lies in wait for the faint vibrations created by a creature moving above it. While hidden under the ice and snow, it can lower its body temperature so that it doesn't melt its cover.

Young Ones

Frost giant hunters scour the icy wastes for remorhaz nests and eggs. The giants prize young remorhazes, which can be trained from hatching to obey commands and guard the giants' icy citadels. Unlike fully grown specimens, young remorhazes gnaw on their victims instead of swallowing them whole.

Full-grown remorhazes are single-minded ambush predators. They attempt to bite prey and trap it against their searing bodies, then swallow their meal whole. Remorhazes eat as much as they can, since they might go months without feeding.

Light blue centipede-like creature that pulses with reddish glow from intense body heat

A Remorhaz is light blue in color but pulses with a reddish glow from the heat its body produces. It is a little more than 20 feet long and about 5 feet wide, and weighs about 10,000 pounds. A remorhaz hides under the snow and ice until it hears movement above it, attacking with surprise.

These great polar worms are found only in arctic areas. The remorhaz attacks on sight, and if encountered in its lair there is a 1 in 4 chance it has a mate and 1d3 eggs; the eggs can be sold on some markets for 5,000 gp each. The HD of the remorhaz determines its length: starting at 21-ft, each hit die above 7 adds 3-ft, so that a 14 HD specimen will be roughly 42-ft long. The remorhaz is ice-blue in colour, with white protrusions along its back and white insect-like eyes. When attacking, the remorhaz rises on the back section of its body and begins beating its bat-like wings. Its attack is blinding, and the larger-sized remorhaz can swallow its prey whole. All remorhaz generate an intense internal heat that instantly destroys any swallowed opponent. An opponent is swallowed and destroyed if the remorhaz' attack score is a 20. When aroused for combat, the internal heat of the remorhaz seeps up into the protrusions on the back of the creature. Non-magical weapons that strike the back will melt, and any physical touch deals 10d10 hp damage.
