Gloomstalker
Large Monstrosity, Typically Neutral EvilHabitat Planar (Shadowfell)
A gloomstalker is a winged predator resembling a wyvern composed of twisting shadows, with glowing eyes and dagger-like teeth.
Hailing from the cursed lands of the Shadowfell, these nightmarish creatures hunt the barrens of that desolate plane, freezing prey in their tracks with their woeful shrieks before pulling them into the sky with their talons to be ripped apart and devoured.
A gloomstalker's proclivity for darkness makes it extremely dangerous at night or in heavily shaded places where it can blend in with the shadowed surroundings. Much more dangerous than the lone hunter is a pack of gloomstalkers. Small packs of three to six are common. Larger packs of ten or more, called frenzies, are often harbingers of a greater evil yet to be seen.
Gloomstalkers were employed by arcanists and the followers of the Betrayer Gods as mounts in the ancient battles of the Calamity. A respectable number of gloomstalkers, now free of their burden, still occupy hidden lairs scattered across the wastes of Xhorhas.
