Tulzscha (The Green Flame) is the name given in Malleus Monstrorum (Role-Playing Supplement) Call of Cthulhu roleplay game guide to the entity described in Howard Philips Lovecraft's story "The Festival". Tulzscha appears as a blazing green ball of flame, dancing with its Lesser Outer Gods at the court of Azathoth. Called to our world, it assumes a gaseous form, penetrates the planet to the core, then erupts from below as a pillar of flame. It cannot move from where it emerges.
