Habitat
Devils and demons of Hell, like kings and knights of the overworld, have a need for beasts of burden. Horses, if you weren't aware, don't do well in sunless hellscapes with limited access to water or ventilation. The denizens of hell have had to make and breed their own. These creatures cannot be bred in the overworld, though they can be summoned through spells like a Courtier's Summon Fiend ability.

Physiology
Though twisted and mutated, they are still analogous to horses, oxen, donkeys, and the like. They may take the form of a horse with six legs and sixteen eyes, or a donkey without legs but a mollusca-like slimy protrusion at the bottom of their body. The images that they present and perform are always twisted and off, never a perfect replica of our realms beasts of burden. Their skin and hair can change tone, their eyes can have different colors, and they can have sharp teeth. Their appearance is often demonic in form. All Beasts of Burden have an enduring set of legs and hooves to climb even the sharpest of stones and most violent foliage. Their skins and fur protect them against the heat of the Nether.

Behavior
The creatures aren’t generally aggressive unless threatened or attacked, much like their overworld kin. They can graze, wander and roam in packs, so long as the habitat they trek through is manageable.
