A language of hisses, huffs and harsh air flow making almost no use of vocal cords. Its speaking often leaves a foul taste of ashes or similar flavors in the mouth of the speaker (though it cannot be smelled as such). It is used by all creatures of the shadowlands, shades, aetherwylds, and fell creatures tied to related places or creatures. Fiends understand it though do not speak it. It is the language of void magic and the dark arts as practiced as well.
