Evil Deities

Evil Deities otherwise known as Demon Gods are legendary figures in the New World, who appeared some time after the defeat of the Eight Greed Kings 500 years ago. Spreading chaos and destruction throughout the land until they were defeated one by one by the Thirteen Heroes.

Background
Not much is known about what the Evil Deities were, or their number. They were immensely powerful by New World standards, their only desire, as far as anyone knew, was to destroy all in their path. It is believed that they were not beings originating from the New World much like the Six Great Gods and the Eight Greed Kings.

It has been speculated that the Evil Deities were in fact NPCs, evidence supporting this are as followed: due to the fact that the Eight Greed Kings possessed a Floating Fortress, possibly their Guild; a powerful weapon which acts like a Guild Weapon and multiple other YGGDRASIL items and abilities such as resurrection after death.

Given the nature of NPCs transported to the New World along with their respective Guild masters/creators and their fanatical loyalty to them, it is quite possible that the NPCs of the Eight Greed Kings Guild were named Evil Deities after slowly going mad from mourning, loneliness and rage which began their hatred for the New World and it's population who killed their beloved masters.

Strength
They were believed to be quite powerful, requiring the Thirteen Heroes to face and destroy each of them one by one.

However most of them if not all did not exceed level 60, some may have been weaker, as stated by the commander of the Sunlight Scripture one such Evil Deity was slain by the Dominion of Authority and it's 7th tier attack spell, which according to Ainz is quite weak.
