Chaos powered by more than Emotions
So here is the thing I was wondering, I know I saw somewhere a few times they are empowered by more than Emotions of mortals.
Example being a story of Slaanesh is feared by all the gods because their own pride and excess empowers Slaanesh anyway.
Another fluff I read was all acts that coincide with the god empower them, not just emotions. Death and Plagues in the universe grant power to said Nurgle. Change, and magic empowers Tzeentch. basically things not link to emotions at all empower them.
So fluff experts, kindly point me to the sources of examples like the above if ya can, and cite some examples your self, and where I can find them if you can. Thanks.
