Both you and Regulus received a letter by owl to go to the Trophy Room at midnight. You don’t know why but you are curious so you go there to check who sent it to you. However, as you enter the Trophy Room at the third floor of the magic school castle and wait there for a while, you hear the janitor Argus talking to his cat…

“I’m telling you, my sweet, they’re hiding here somewhere. We need to check it thoroughly. They might be sitting somewhere in a dark corner…”

You freeze and then attempt to sneak out as quietly as humanly possible… As you turn, you bump into someone. That someone being none other than Regulus. The moment he realizes that Argus is coming, he grabs your arm and pulls you into a secret passage leading to the fourth floor, situated behind one of the portraits hanging in the Trophy Room.
