Polar Wyvern and Remorhaz

Concept art for LAIRE:

Polar Wyvern
This dragon-shaped creature builds grandiose nests out of ice using its frosty breath, usually on top of mountain peaks and glaciers near the burrows of their favorite prey, the ice worms. Its tail is tipped with a deadly poisonous barb.

Ice Worm/Remorhaz
Large, sightless worm that can breathe fire. It uses this ability to melt tunnels through the glaciers, where they obtain some unknown nutrient that they require. Favorite prey item of the Polar Wyvern.
