Abyssal
The language of the Void Elves and the Demons of the Void.
Due to some similarities, it is believed that Abyssal is an off shoot of Primordial. Because of this, some experts theorise that it originates from Nosferi, the Vampire language.
There is little proof to support this theory, though. If there are any old records that may provide insight on the language, it is probably protected by the Void elves, as they are very secretive.
