Across the vastness of Galaxia, many Celestial Entities use their power to create new Dimensions, even their own custom Universes.

In their respective Universes, those beings are bound neither by the rules of Time nor by the fabric of Space. As the ones who hold the tangled strings of Destiny, they are perceived as Almighty Gods.

In order to prove the supremacy of their creations or just for entertainment, sometimes they clash with each other using their Champions as proxies. The Project CrossOver will present some of those epic fights.
