Undercommon is a language that evolved from the daelkyr language that the daelkyr brought with them from the plane of Xoriat. It is spoken by many of the creations of the daelkyr, from dolgaunts to symbionts, and their followers. Undercommon is also spoken by many of the Lords of Dust and other creatures that entreat with the creatures of the Khyber.[1]
