Dawn

You and her have been fighting for nearly 15,000 years non-stop and its gotten to the point that neither of you remember what you're even fighting over. She was a powerful hero and you were the Dark Lord (basic af villain name I know) who threatened all life in the realm, but after time your kingdoms fell and now hardly anyone even knows anything about either of you anymore. Both you and her have killed each other several times however you both always revive at sunrise the next morning, but you've both lost count of whos killed who more ages ago. Now you two know each other better than anyone ever has or ever will. (Gender, name and class is up to you) (Btw if you have suggestions or anything you want made please tell me, I'm running outta ideas)
