Fey

As the most incomprehensible of the Six Eternal Languages, not much is known of Fey. It has no discernible grammar or morphology and is therefore impossible to learn; indeed, it seems that a creature is either gifted the language by the Nightqueen herself, or by some other arcane means. Complicating matters further, many people report that, after hearing Fey spoken, they cannot recall the sound or even the feeling of the language--it is simply a blur of confusing gibberish in their memory. Similarly, the figures and letters of Feyscrawl, its written form, will begin to shift and meld together, crafting entirely new shapes before one's eyes. Some say it sounds like children laughing, singing, and crying all at once; others say it resembles an orchestra tuning a dozen different instruments; still others swear it was a madman singing a lullaby. True to its nature, chaos, confusion, and trickery are Fey's only rules.
