Two million years ago, chaos reigned on the planet of Gaia, throwing a very advanced human civilization into an apocalyptic period.
Meteors struck the planet everywhere, destroying more than 75% of all the existing life within just a few months. Fortunately, by that time, mankind's space program was advanced to the point that they managed to evacuate those with the potential to develop society to other star systems, leaving behind the unfortunate.
Meanwhile, the animals mutated into terrifying beasts and got rampant, bringing the rule of the animal kingdom to the planet. It wasn't just animals. Several species of plants were also turned into monstrous plants.
To counter this, the Guardian God, an entity of immense power and wisdom, descended upon the planet.
Through divine intervention, he introduced runic magic, a system that allowed mortals to harness the energies of their world, and genetically altered human DNA, granting them abilities to stand against the beasts.
