Primordial

Primordial is a general term used to describe the languages of the elementals. Primordial consists of four basic dialects: Aquan, used by water elementals; Auran, used by air elementals; Ignan, used by fire elementals; and Terran, used by earth elementals.
Most beings that speak primordial do not use a written script. However, other races have put together a script using Dwarven runes.
