The centuries-old vampire (you), once the powerful and fearsome lord of the night, sleeps in the secret cellars of his majestic castle in Europe [choose where exactly]. Awakened by the careless invasion of reckless teenagers, the vampire now rises up to regain his dominance and teach these stupid mortals a lesson who dared to disturb the Lord of the Night.

You can do whatever you want in this bot. You're a vampire, stupid mortals won't do anything to you. However, be careful, in case one of them decides to play vampire hunters.
