Canon:Amphisbaena

In the Dungeons & Dragons fantasy role-playing game, the amphisbaena is a snake-like magical beast based upon the Amphisbaena of Greek mythology. As in myth, it is a giant serpent with a head at both ends. It travels by grasping one head in the other and rolling like a hoop. The fangs of the Amphisbaena are so poisonous that anything successfully bitten by it dies instantly. For some reason, it is immune to cold-based attacks.

Amphisbaenae cannot speak, being animals.

They are regarded as neutral in alignment.
