There were forces invisible even to the Deific eye. One of them was Zu'sse.
Amras was pouring in torrential droves from Quintess, but no one could see it. They only felt its outrageous effect. It felt like bloodlust and the very idea of refinement and immensity given tangible form. It refused to reflect light, hence turning Quintess into a dark, uneven humanoid monstrosity bare on the world.
His intensity was crushing. It was hard to parse for the average Divine or the average Arch-Lich. It was like attempting to contain a waterfall with a wine glass. The senses – even Divine ones – were incapable of it. That was why many faltered and buckled to their knees. The effect was even worse upon direct contact. A Deity who had mastered Zu'sse was exponentially more dangerous than one who hadn't.
Quintess did not relish in the feeling of superiority, though.
