Things happen. Gods die, and Gods are born. Fate is sealed when birth occurs and ends when life ends…...for most at least. A few are given the opportunity to change their fates, and sometimes, even change the fates of the Gods as well. What once was a group of average adventurers has become something more, due to a prophecy as old as the multiverse. Time continues, and they continue to struggle against their fate.

After that, take a look at your wiki. There is some more helpful info there.
