The earliest appearance of this language is unknown, many accept that it is as old as the Celestial language and predates the existence of any creatures of Isekai. The creatures that speak this seem to be high-class entities or cult leaders, lesser Demons appear to avoid this language entirely and are unresponsive or fearful when they encounter a being that can speak this language. Those that choose to study this language and are outside of the prior classifications usually invest their time learning this language are Scholars interested in knowledge itself or creatures that want to uproot, destroy and understand those that worship dark entities. The script for Abyssal is harsh, with jutting lines that look more like scratches instead of strokes and it is said that when the language is written on a solid surface that the depth of the scratches can convey additional meaning.

The Fire Islands have many such places that have been preserved as a source of history and study, despite there being a critically low amount of cult activity in that region the Nephilim population seeks to understand much about its past and how to repel demonic beings from visiting their world again.
