The ability to speak and comprehend the Archaen language, the tongue of the terrible Fomori. It it said to be one of the languages which predate the existence of the world, like Thari and Cilaghai, and like those tongues it is said to hold much power; few of the younger races dare study it, though, for Fomori are said to consider their tongue being spoken by outsiders to be a grave insult.
