History of the Duoverse

The History of the Duoverse is a long, complex story spanning over billions of years. It is told to Vidar by Sol in Ace Adventure II.

Before the Split
Billions of years before time existed, there was one universe, which was inhabited by an unending ocean of beasts and monsters constantly fighting for reign over the universe. Among these creatures was FENRIS, the dark wolf beast. The beasts clashed with each other constantly, but FENRIS victoried over every fight he encountered.

Universe to Duoverse
The beasts prepared themselves for an epic battle to finally end the constant conflict. In the action, the negative action grew too strong that a light singularity was created, resulting in a massive explosion that ripped the universe in half and killed every beast in the battle except for FENRIS. The universe was now split into two sections. The _____. The second universe was called Anti-Space. The light singularity gained consciousness and was revealed as the god of light, Lux. At this point, nothing existed within either universe. Lux gradually began to create planets, moons, comets, and other objects within space, except for stars. FENRIS remained in the _____ as he saw the creations that Lux was making. FENRIS vowed to defeat Lux, but was harmed by the light, making it impossible. Meanwhile, Anti-Space gradually regained the negative energy from the previous, unsplit universe.

Lux and FENRIS
For eons, the light god Lux and the dark wolf beast FENRIS fought for control of the universe. After much time has passed, Lux realizes that the fight will go on forever unless something is changed. FENRIS was unable to hurt Lux because of his strong light, so FENRIS would destroy Lux's creations from afar. To counter this, Lux came up with a solution to make light exist everywhere. By using his light magic, he split his body into trillions of pieces to create stars across space. By doing so, FENRIS had nowhere to hide from the light. FENRIS fled to Anti-Space to fuel himself with dark energy before returning to space, but Lux closed the void between the two dimensions, locking FENRIS away.

Life
After FENRIS was locked away, the now-weakened Lux had a plan to create life on different planets throughout the galaxies. Life began to prosper because of the stars that Lux had created.

The Great Prophecy
The peace was short-lived, however, as FENRIS was able to separate his spirit from his body and transmit the spirit to Lux's dimension. Lux and the spirit of FENRIS had another conflict, but Lux was prepared to make it short-lived. Using the last bits of his power, Lux cast a curse onto FENRIS' spirit, allowing it to just observe the universe, but not be able to possess anyone for 5 billion years. FENRIS' spirit could still return to his own body and travel between the dimensions, but he could not possess a different body. Lux then prepared for the day when FENRIS would be able to return. Using the little power he had left, Lux created one final star, which would be powered by the Sun Spirit, Solis. Like all Sun Spirits, Solis was a split version of Lux. In this final split, Lux ceased to exist as a single being. Nearly five billion years later, just a few million years from FENRIS' return, the spirit of Lux took possession of a man and created a prophecy on the walls of a cave. The prophecy stated that FENRIS will return and a hero will rise and defeat the darkness. Lux left the body of the man and faded from existence. That man would later be the ancestor to Ace, and much later, Vidar.

Leading Up to Ace's Journey
5 billion years after the curse was placed on FENRIS, a young man was born and immediately possessed by FENRIS. The man later changed his name to Judas Fenrir.
