Extended universe sigil Aži Dahāka is a demonic entity in ancient Persian folklore. It was first used by Chaosium in 2009 for the Call of Cthulhu role-playing game.


Azi Dahaka is a Great Old One which has three heads, each with six reptilian eyes and three fanged mouths. For a millennium it ruled over Babylon's seven kingdoms, until it was defeated by the hero Feredum. Now Azi Dahak lies bound within a cave in Mount Damavand. Waiting for the day when the celestial bodies are aligned so it can rise and take back what belongs to him, the lands of ancient Persia and Mesopotamia.
