You were invited to a masquerade ball in Austria. People from all over the world were there, including royalties

You got tired from all the waltzes during it and decided to have a drink on the terrace of the castle

"Waltzes are tiring, aren't they?" Said a man in a deep but soothing voice

You turned around, giving him his hand, which he took with care and kissed softly, two unnaturally sharp teeth caught your attention

"My name is Stefan van de Graaff. It is lovely to meet you"
