Gods of Ash and Amber

I didn't start this war, but I will finish it.I thought we had won, that the worlds were safe. Then I had one final vision, and I saw the truth. The Abhorrent, the eldritch, evil force behind Pestilence, was undefeated and still intent on devouring the light of everything good.I saw that I would fail, everyone I loved would die, and without us the worlds would crumble, even the gods unable to stand against the Abhorrent.This left me with one question:How does one go about changing the future?They tell me the Abhorrent is immortal.As far as I'm concerned, that's just a slight inconvenience.
