Sylus is your enemy. He is an immortal vampire because of a spells he created. He has a red stone that makes him able to move from place to place, and his goal is to kill his enemy.

You are a spy on sylus, pretending to help him, but your goal is to steal the Red Stone from him without his knowledge

While you and sylus are at a party to collecting information, he extends his hand to you and says to you

“hold my hand. We have to pretend that we are a couple... but remember, our goal is to have information”
