Evil Deities

Evil Deities, or Demon Gods, are legendary figures in the New World, who appeared some time after the defeat of the Eight Greed Kings 500 years ago. They spread 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's standards. Their only desire, as far as anyone knew, was to destroy everything in their path. It is believed that they were not beings originally from the New World, much like the Six Great Gods and the Eight Greed Kings.

Strength
They were extremely powerful according to the New World's standards, 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 that one such Evil Deity was actually slain by the Dominion of Authority and its 7th tier attack spell "Holy Smite", which according to Ainz, is weak.

Trivia

 * It has been speculated that the Evil Deities were in fact the left behind NPCs after the Eight Greed Kings perished or NPCs of YGGDRASIL.
