In the distant kingdom of Stygia, the priests of Set perform strange rituals in the heart of darkened temples.One of the worst is the Call of the Swarms of the Snake God. Nobody except the evil clergy of Set knows how to proceed the ritual, but what is certain is that it ends with the invocation of amphisbaenians. These two-headed snakes with fangs dripping with venom then creep into a corpse through the nostrils and animate it with an unholy life, blowing up the eyeballs if they are still in place. These walking corpses have therefore instead of eyes the two heads of the amphisbaena pointing in the empty sockets.

In addition to the attack by the undead (1d6 damage), each head of the amphisbaena tries to bite every round to inoculate their poison, suddenly arising of the eye sockets and retracting the second after. Bites that are benign do not damage but if a saving throw versus poison is failed, the victim convulse for 3d6 rounds. Two simultaneous bites on the same person entails a saving throw against death.

Killing the undead does not necessarily kill the snake: if it is cornered and alone, it is killed automatically by the characters if they specify it. Otherwise, in a melee, the amphisbaena has a chance to escape and animate another body.

They are repelled by clerics as ghouls.
