... I do not believe dark elves of Layonara have their own sign language the way RA Salvatore's mythos had them.
What does the dark elf ear allow you to speak - dark elf, undercommon, Deep or what? I am very confused over which language the dark elf ear actually is giving the user.
Thanks but none of these answer my original query which was - And of course it is the language of dark elves, but my query was, which one? And by extension, which language do dark elves actually speak then, both in front of slaves and also to each other, assuming they are different.
