Nemesis

"Do you want revenge?" it whispered into her ears, "don't worry. Thats exactly the reason why I exist."

The deities of revenge stands firm again. They have grant humans to revenge others. Although, I cannot say that they will do this for free.

The Nemesis is unpredictable. We can't know if they're morally good or bad. Are they even on our sides?

Or will our plan to bring peace be backfired by them?

The story is redacted a bit and vague. Humans cannot know and store every information, although the imagination can interpret.
