From Threesong
"Infernal" refers to the Neo Inferno's unique language and material culture. Acheron, the plane of chocolate sin, uses Celestial and is much more closely tied to the lawful planes than the evil. "Tartarian" refers to Hades, Gehenna, and Carceri, the domain of the Yugoloths. "Abyssal" is the same language Iosefka knows and applies to remnant demons, but it's also used by xXxRiverxofxLyexXx in Pandemonium alongside Ysgardian Celestial. Ysgardian Celestial is distinct primarily because it uses runes instead of constellation-letters, and these runes are also used in The Beastlands, Arborea, Limbo (by gith), and Pandemonium (by gith and xXxRiverxofxLyexXx).
