Before the universe, there existed only Chaos, a formless matter. When the gravitational force of Chaos compressed it to an infinitesimal point, it exploded and formed the Firmament.
Systems of planets and life evolved from the transfiguration of Chaos, as did dense gem-like Shards scattered across worlds.
These Shards radiate densities of time and gravity, causing the evolution and morphology of species, and have been manipulated by them to imbue select members of each race with extraordinary powers.
Shards are now found primarily on planets that have remained inaccessible due to interstellar clouds and gravitational forces.
Cosmic events like solar storms and the collapse of stars create brief windows to access these Shard-rich planets, and five powerful races rapidly descend upon them to battle each other in their quest to harvest Shards.
