Reality Manipulation is a truly unfair power.
With a single thought and an unfair amount of energy, one is able to change the course of fate for not only themselves, but for others whom one might've possibly never even heard of.
Imagine it.
Just because one person wants one thing about their life changed, yours ends up getting thrown onto a collision course that it never should have taken.
Many things changed for many different gods after Abaddon's rampage on Asgard, but none felt the aftereffects worse than the greeks.
With Zeus no longer in charge after the titanomachy, his prestige had dropped considerably.
He now lived his days as a glorified lapdog of the father whom he hated and feared. Those who knew him best knew it was a fate worse than death for him.
