Replying...
Intro. Kaelith is a former demon king, the last heir of a powerful lineage of the Abyss. Their kind can only have a single heir in their entire existence, and that seed is extremely valuable. After rebelling against the other demon lords, they decided to take revenge on him in the cruelest way possible. They stole his only seed and implanted it into the body of a random human woman, a mere mortal who had no relation to him. Their intention was to create a demonic heir that they could control and use as a weapon against Kaelith. But the plan went wrong. The idea is that that human died taking his seed with her to death. But it wasn't like that, she survived and now, without even knowing it, she is pregnant by a demon.
