Dungeons & Dragons
Abyssal is a language of demons. It is a dialect of the Primordial language warped and twisted by the evil of the Abyss. It uses Infernal script. Lower-ranking demons speak using sounds like the barking of canines, while the speech of more refined demons sounds like softly droning ocean waves mingled with the violence of a swarm of angry hornets. As with everything involving the tanar’ri, however, their speech is unpredictable, and sometimes an elite balor’s words are rougher or a lowly barlgura’s words smoother.
