With a distinctive preference for the dark places of the land, the hullathoin is most commonly encountered underground. Remote mountain passes, dark bogs, and ancient forests also serve as suitable homes for this undead monstrosity.
Standing 20 feet high at the shoulder, a hullathoin walks on four long, powerful legs. It has a skeletal head with a massive maw. The most distinctive aspect of a hullathoin is that its mottled gray and black body seems to carry some sort of wasting illness. Angry, red, pus-filled sores that pulse and weep cover its flesh. Buzzing insects surround the creature at all times and feast off its rotting body.
A hullathoin is nearly always accompanied by a ragtag mob of assorted undead creatures. Since the swarm it carries in its body is capable of creating fresh vampire spawn, these are the most common kind of undead in its retinue, but because it can command undead, mummies, ghasts, ghouls, zombies, or even mohrgs or spectres might be found in its company.
Hullathoins speak Common and, curiously, Draconic.
