I'm going to use it in my fanfiction, but it's fine if you want to as well!

A revenant, someone who was so wronged, and so angered by it, that they unleashed an ungodly amount of power. They pull their energy from the cosmic force, giving them a few innate abilities.

Here is what makes someone a Revenant.

1 They must experience a betrayal, and become wildly angered by it, so much so that they fight death and go on just to kill whoever wronged them.

2 They must have Force Healing and Force Drain

3 They are ageless, but not immortal or invulnerable, they can be killed by another person, as long as they are force sensitive, as the mind of a Revenant is greatly weakened.

4 They must have a force bond with the person they are getting revenge on.

Please credit me when using, you don't have to but it's nice.

I think they would be used best as a simple villain or metaphor, your writing ideas below!
