Universe 1929294 is the universe Key Mace is from. It is mainly based on the Yu-Gi-Oh! Series.

Pre-creation
The only thing existing then was Numeron Dragon.

13.8 billion years ago, Creation
Because she was so lonely, Numeron Dragon used nearly all her power to create everything, and used the last of her strength to shed a tear that flew through space for 9.3 billion years.

What she created was the Ocean of Otherworlds and the World of Darkness.

In the Ocean of Otherworlds were two "empty" worlds, the Astral World and Human World/Original Dimension, while the World of Darkness contains the Duel Monsters Spirit World, itself being 12 dimensions instantly filled with life.
