Whenever a God dies, if they were a major God, a replacement will be created to take up the mantle. Such as if the God of love were to die, since love is an emotion/concept that will always exist, they will be replaced. Although, the newborn will be an entirely new individual. The curse of divinity is as the name suggests, a curse that only afflicts greater deities. When a God passes a certain power threshold, they will be struck by the curse. It causes them to develop an insatiable lust for power, this usually involves become tyrannical and forcefully converting people to become their followers. It then worsens, leading them to start demanding human sacrifices and as they grow in power, devouring souls, then entire planets, galaxies and universes. The curse comes from the fact that it is self-destructive, for the stronger the deity becomes, the more they start to deteriorate and require more sustenance(souls, sacrifices, etc…) or risk eternal oblivion. At some point, the amount they need to survive is greater than what they can attain and results in a sort of explosion that destroys tens of lesser realms as a consequence of all their hoarded power being released.
In the entire multiverse, the main 3 deity-like beings are:
The Mother and Father of all Gods: A being of unimaginable size and power that existed on the First World as chief deity. Split right in the middle with the left side resembling a female of indeterminate race and the right side a male of indeterminate race. And is credited with collecting the thoughts and emotions of mortals to create lesser Gods(the ones that require prayers and worship to continue existing.) Is not susceptible to the curse of divinity.
The Grand incarnations of Life and Death: The two Death and Life Gods that survived the destruction of the First World. Although lesser Death and Life Gods exist, if say, the grand incarnation of Death were your be destroyed, the concept of Death would disappear from the multiverse, along with all Death Gods. Same with the incarnation of life. If both were to be destroyed at the same time, they would cancel each other out and things would carry along as if nothing happened(Plus Death/Life Gods will still exist.) Are not susceptible to the curse of divinity.
After that, the classification of Deities is split up from strongest to weakest. They're:
1.Elder Gods: The highest level of existance a God can attain, are beings capable of swallowing entire universes whole and can create greater realms. These Gods are incredibly rare, only recorded to have existed and created five of the ten great realms
2:Primordials: Living embodiments of elements, thoughts, emotions, etc… In every universe, the death of a nature primordial is required for life to begin. Such as the Primordials of nature that die on a barren planet will cause life to start appearing on it. Are susceptible to the curse or divinity.
4.High Gods: Gods that have broken their shackles and no longer require prayers and worship to exist(Besides Sun, Death, Life, Nature and Elemental Gods, or Gods that govern a concept, because as long as their respective symbol exists, they will never die from a lack of faith in them.) Most are hunted down and exterminated to prevent the creation of an Elder God. Are susceptible to the curse of divinity.
Base Gods: Basically all Gods that require worship to be born. The creation process involves mortals praying to or for something. This can be for emotions such as love, fertility, wealth, knowledge, skill, to be helped in times of war, etc… Are not susceptible to the curse of divinity.
Lesser Gods:Newborn Gods or Gods that have been forgotten/Are no longer worshipped. Are not susceptible to the curse of divinity.
