Desert Bestiary: Nasnas and Lammasu

Desert mythology is full of legendary creatures that can be adapted into a fantasy RPG setting. Two new entries for the desert bestiary come right out of these tales of the desert. The Nasnas comes from Arabian myths and is traditionally portrayed as a type of djinn. I have transformed into a demon for the desert bestiary. From Mesopotamian mythology comes the lammasu. This creature has previously been adapted for use in D&D, but was left out of 5e.

Desert Bestiary: Nasnas

The nasnas is an evil demon that preys on unsuspecting desert travelers. It is a horribly misshapen humanoid with one entire side of its body and head missing. Because of this deformity the nasnas moves very slowly and must use trickery to capture prey. The creature lurks around oases using its shape-shifting ability to take on the appearance of a hobbled old person. The nasnas uses this disguise to lower the guards of its targets. Once a traveler lets their guard down, the nasnas reveals its true form and strikes at its prey, paralyzing and killing them.

Desert Bestiary: Lammasu


The lammasu is a classic D&D creature with a version appearing in every Monster Manual up to 3.5e. Although this creature usually appears in the game as a hybrid between a human, a lion and a bird, another version appears in Mesopotamian mythology that is a winged bull with a human head. This is the version that appears in the desert bestiary.

Lammasu’s are celestial beings that live in the desert. Even though their alignment is lawful good they rarely interact with the denizens of the sands often ignoring evil that occurs within their own territories. However, the lammasu are servants to deities and will always act when called upon by a lawful good god.
