Go through the door(a)
From Create Your Own Story
You open the door and walk into the blinding light you had seen before and it releases you. Opening your eyes you see that you are in a large room. Escher and Musiea on the other side of it. On the ground of the room a circle that is about half the size of the room. You walk closer to the middle to the room and after about 20 steps you reach the circle and you see sparks around your body as you walk over it. Moving your hand back it seems like there's a barrier preventing you from leaving the perimeter of the circle. Escher and Musiea walk through the circles barrier too.
"So i guess in here is the clashing grounds." Escher says, taking out his longsword and pointing it at you. Though you about 30 feet away it seems like its right in front of you.
Musiea pulls out her rapier. "So this is it."
You unsheathe yours. "This is it."
Quickly, Escher runs up to you and slashes his sword vertically downward. You sidestep it and try to cut horizontally while he cant block but before your sword reaches him Musiea lunges her sword in between yours and Escher's body.
Escher and Musiea begin a flurry of attacks as you try to avoid or block them all as they come. Escher finally hits you with the broad side of his sword pushing you back a few steps. Musiea, who you can tell is exhausted makes a lunge at you.
