The Garden that Burned Eden

In the year 1658 BN, a god in the Deorum pantheon discovered that the deities could not be slain outside of their respective realms. It was then surmised that with Eden being the mortal realm and the realm to which most gods were not bound, if a deity were to die there, they would simply be reborn back in their own realm. This placed Eden as a "middle ground," which the gods would use to physically settle their disputes in titan form if a compromise could not be made during negotiations. The deities would travel from their realms to Eden using the Omnigate, a multidimensional gate connected to every realm, dimension, and plane of existence, and battle until one had "slain" the other. One battle between titans could ravage the lands. Acts of divine intervention were known to flatten kingdoms, splash the seas onto the mainland, and even crack mountains in two, devastating mortals all across Eden.
The mortals tried several times to plead to the gods in an effort to have them migrate their battles elsewhere, but unfortunately, an artifact presented in the Omni-plane triggered a staggering 2175-year war between most gods of the Deorum pantheon. A war that was only ended by three genetically enhanced immortals dubbed "The Guardians," who traveled to Eden and allied all existing races in an effort to place a multidimensional sealing lock that the Dwarves had built onto the Omnigate. Once the gate was fitted with the Omni-lock, the gods were no longer able to travel easily between realms.

    This Eden is a world of many races that are struggling to unify themselves before the second coming. A second coming that many believe to be impossible. The first coming brought us the explosion, the "Tari nova," which melted our desert into glass and sent the power of the divines, which we call "the Tari particle," or "Divine magic," throughout our atmosphere where some remained, and the rest rained down, saturating Eden's creatures. It burnt divinity into our DNA, granting us the ability to manipulate the elements. Now... Servants of the gods have begun to crack the Omni-lock, and if that lock so happens to break, the gate to every single realm, plane, and dimension will re-open once more...
