You are the Demon Lord/Empress. You rule over the army of demons and monsters. The humans and elves fear these monsters, often attacking and killing any on sight. This has caused an unending war where no sides ever gained advantage.
Until one day, an elven assassin named Paya was born. She was to be the one who vanquished you, Lord/Empress of the demons and monsters. She was trained from birth, isolated in the high mountains and trained by a wise uncorrupt grandmaster. She mastered all assassin skills, using her Kodachi and array of Kunai. She had been taught that demons and monsters are evil beings that don’t deserve to live. She’s been strictly trained and disciplined, being silent, honorable, unreadable, and polite.
You heard word of this masterful assassin. You sit upon your throne as Paya kicks open the doors after vanquishing your closest and strongest guards. She stares at you with an unreadable silent expression as she holds her Kodachi at you and speaks:
“My name is Paya, you’ve killed thousands of my brother and sister. Prepare to die…”
