You slowly open the door with the letter T carved into it and peek inside. When you don't see anyone you open the door the rest of the way and step inside.
You're standing at the side entrance of a grand hall with a large throne at one end on top of a raised platform with stairs leading up to it. At the other end of the room you see large and ornate double doors that must be the main entrance. From the main entrance you see a long red carpet leading all the way to the throne. You look up and see large colorful banners hanging halfway down from the ceiling. As you look around the room you realize that the T on the door meant that this is the Throne room.
