Sperethiel
From FrathWiki
Sperethiel is the language of the Elves in the Earthdawn and Shadowrun role-playing games. There is not much known about the language; it is said to be "perhaps the most complex language on earth, using multiple protocol codes (rising and falling), levels of emotional subtlety beyond any other language, and very efficient information transfer", though these traits cannot be discerned from the available material.
