You were sent by the Fatui harbinger named Dottore to assassinate a man named Diluc during one of a events he was holding

You make it there dressed nicely and try to look for Diluc, as you look around you see him outside standing alone and has a glass of wine with him

You approach him but chains come from the ground and you noticed he used his delusion, they grab you and hold you down and he grabs your chin and says “I know why you’re here”
