Twilight stood before the rectangle of light, ever tempted to walk through it, but she waited until all of her magic was restored first before she would walk through it.
An hour or so later of standing still, her magic fully recovered. She would learn to use it more sparingly next time she encountered a Denizen. She was just thankful that no Denizens had come after her while she waited in this dark hallway.
Steeling her nerves, she stepped through the rectangle of light, not know what to expect.
"What the-?!" She had stepped into what was probably the most out-of-place room in the entire tower. It looked like it had come straight out of Sugercube Corner itself, with balloons and party streamers, everything party-related strewn all over the room. And Twilight saw Pinkie Pie standing in the middle of the room, sitting dejectedly in the middle of the room, her hair straight, and tears rolling out of her eyes and falling to the floor.
"Pinkie," said Twilight. Pinkie Pie's head instantly turned towards where Twilight was standing, her eyes going wide with fear at first glance, before turning to relief when she saw the look in Twilight's eye; her look was not that of a Denizen.
"Oh, Twilight!" Pinkie ran across the room and threw her arms around Twilight and broke down, crying. "I've been running away from Rainbow Dash for a long time, now! The look in her eye, it's so scary! And she has a fireaxe and keeps trying to kill me, and I have no idea where I am, and, and, and-"
"SSsshhh, it's ok, Pinkie," Twilight comforted her friend as she explained everything that was going on, where she was, and what was happening.
"Applejack, Fluttershy, and Rainbow Dash are all dead?!" Pinkie exclaimed in disbelief. She cried even harder this time, tears now opened streaming down her face and dripping off her chin.
Twilight waited patiently for Pinkie Pie to calm down as she held her friend in her arms. Eventually, she did calm down. She removed herself from Twilight's embrace.
"How exactly did you get to this...this..." Twilight gestured at the room before them. "....this room, anyways?"
"Well, like I said, I ran away from the Rainbow Dash Denizen, and I managed to lose her, but then I got stuck in this room. I think the tower's mocking me, now, sticking me in a room like this. I didn't know why Rainbow Dash was doing that to me, and I was too scared to go anywhere else, so I just stayed here, and....well....cried...." Pinkie said.
"Hm. Well, now you know there's a way to beat the tower. I can't promise either one or both of us won't die, but we should be safer if we go through it together." said Twilight.
"Of course we're going together!" said Pinkie. "I can't just let you go through it alone! I'll be by your side, every step of the way." Pinkie reassured her friend.
"Thanks, Pinkie." Twilight smiled gratefully. "Where did you come in from, anyways?"
"From here," said Pinkie. She gestured for Twilight to follow as she walked over to an elevator. The elevator's arrow currently pointed to the letter G, which Twilight assumed meant 'Ground," even though from everything and everywhere she had been through leading up to where she currently stood, she knew that the floor she was on was obviously not 'Ground,' but right now, with this tower, anything and everything went. Besides, it probably meant 'Ground' for this floor. The arrow could also point to 1 and 2.
"I jumped into the elevator and slammed a random button, then I ran out of it and collapsed in the middle of this room right here." said Pinkie.
"Well, what are we waiting for?" asked Twilight. "We got our friends to save."
