Among the malefic horrors spawned by Hyperborean sorcery are the feral blasphemies known to Cimmerian hunters as Frostcrawlers. These rapacious things ghost through the mist-cloaked forest, hissing to themselves and slithering in search of prey.
No natural beast, a Frostcrawler is somewhere between a serpent and an eel, yet with aspects resembling neither creature. A serpentine tail thrashes through the foul-smelling swamp water as the Frostcrawler glides towards its intended prey, while a roughly humanoid torso rears up from the depths to lash out with surprisingly powerful arms and multi-jointed fingers tipped with vicious claws. Its mouth is that of a sea-snake or giant eel—an ugly slit in its reptilian face, lined with rows of needle-like shark’s teeth.
Some of the few living witnesses to have seen a Frostcrawler describe it as a throwback from an earlier age, when crocodilian beasts claimed the world as their own. Most survivors are not educated enough to make such an assumption, and merely point to Hyperborean sorcery, citing the creature as the brutish, malformed result of black magic tainting everything it touches.
