Goddeath

Goddeath is a condition that afflicts all perpetrators of the Godwar. The Titan known as Itself, AKA the Wildhunt has trapped them within demiplanes using energies from both the ShadowFell and the Empty. These demiplanes, or domains of dread as they are colloquially known, are shrouded in impenetrable mists that prevent traversal barring a few exceptions on a case by case basis.
Each of these domains functions as a prison for the proclaimed god. Simultaneously torturing the god it holds, while inhibiting their full power and influence on Na'Endreth. The Domains of Dread use their prisoner self sustaining battery. Every souls that once fueled the deity is trapped within the domain subject to the same rules that torment their god, becoming prisoners in their own right.
Goddeath is a flimsy yet sustainable means to an ends. Considering the soul count an impact on history, Gods are virtually indestructible. Now all they can do is influence the world through patronage and dominion.
