This creature looks like a puffy and bloated human-sized whitish-yellow maggot with purplish veins pulsating under its fleshy form. A vaguely humanoid head sits atop its body and its facial features are twisted and distraught as if the creature was in a constant state of pain. A pair of large, downward-curving horns juts from its head, just above its sunken eyes. Its mouth is lined with filthy and sharpened fangs.

Abyssal larvae are believed to be the final form of an evil soul deemed too weak to become a demon and too weak to become the servant of a demon. Another theory suggests that the larvae are the imprisoned forms of slain demon princes and lords. Whatever their true origin, abyssal larvae are plentiful throughout the Abyssal planes, and are some of the most disgusting and loathsome creatures encountered.

These creatures feed on anything they can consume, be it rotting carcasses, freshly slain creatures, and even waste. Consumables are first liquefied through a process requiring the abyssal larva to regurgitate stomach acids onto its meal. As the food breaks down, the larva slurps it up and consumes it.

While loathed by the more civilized, some demons, such as dretches and babaus, savor the juicy flesh of these creatures and often engage in hunting expeditions across the Abyss, killing and devouring as many of these creatures as they can find.

Acting as if almost mindless, abyssal larvae attack any living creature they encounter. They have no real tactics other than swarming a foe and biting relentlessly. These creatures fight until destroyed.
