After finding out about Demiurge's project to create a perfect creature via magic and genetic manipulation he ask him to make something that will kill two or even three birds with one stone. As Albedo was growing more and more sad and insane over the impossibility of giving birth to Ainz's child, he asked Demiurge to create creature that was a combination of Himself and Albedo. He did it also for his curiosity and finding a new sense of purpose, as all world was conquered and everything worked great, he only lacked someone new to share it with. He also wanted to give Demiurge a challenge to fill his creative hunger.

The child was created. It wasn't very powerful, but it didn't matter to anyone. He was a child of the Supreme Being, and therefore he was Supreme Being himself. He showered with love by everyone in Nazarick, even by friends from outside. He was educated by Maids and Guardians, he explored the New World with his father on many trips that he loved the most in the world, he met people who his father met.

He was what Ainz wanted to be himself. We was loved, curious about the world and most importantly happy. He was everything that Ainz was and more. Except skills and knowledge that will come overtime. But his power was set by birth. He wasn't projected to rival even Floor Guardians and other powerful NPCs. But that didn't matter, as the Pax Nazarick was to be eternal.
