Shiväisith

Shiväisith is the language spoken by the Dark Elves. It was created by linguist David J. Peterson and introduced in Thor: The Dark World. While the Dark Elves can speak other languages, it is their native tongue and the language they use to converse among themselves.

History
As the language of the Dark Elves, Shiväisith has been spoken probably as long as the Dark Elves have existed, before the creation of the Universe of matter and light.

First Dark Elf Conflict
Malekith and Algrim discuss in Shiväisith as the Asgardians descent on Svartalfheim. Orders are also relayed in Shiväisith to the Dark Elf soldiers.

Second Dark Elf Conflict
Shiväisith is spoken by Malekith and Algrim while discussing their plans of revenge on the Asgardians and the return of the Universe to darkness.
