As the four began to close in, the trio backed up, trying to avoid every attack that was directed to any of them. Twilight attempted to hit them with blasts of magic, but only half of the blast dealt damage. The other half didn't do anything or was deflected, nearly hitting one of them. As the trio was cornered, Rainbow Dash looked down at her left hoof and sighed.
On her hoof was an engraved cross. It was slightly glowing and illuminated a little area around it. It did this every time a threat was either nearby or when something from hell had escaped. It began to glow brighter as the three monstrous ponies and creature closed in.

Rainbow Dash used her other hoof and covered it up, knowing it was probably a bad idea because of the other symbol on her right hoof. As Applejack was about to attack, Twilight and Pinkie Pie jumped out of the way and Rainbow Dash dodged the attack, sliding underneath the earth pony. She pulled herself upright and leaped onto the monster's back, leaping out of the room. It turned around and Rainbow Dash pulled herself up onto a low beam, making sure to leave herself exposed to the faint light that was coming from a single candle nearby. It growled and attempted to attack Rainbow Dash, but Rainbow leaped to the next closest beam. Fluttershy quickly climbed up a broken beam and lunged Rainbow. She pushed Fluttershy down to the floor, causing the other pegasus to hit the monster and Dash balanced herself with her wings before she fell. What she didn't notice was the small burn mark she had somehow made on Fluttershy.

She watched as Twilight and Pinkie ran away, Rarity and Applejack following not far behind. she looked back down at Fluttershy, who was trying to get off the monster. It flung her off and Dash quickly got away before it could attack her again. As soon as she caught up with the four ponies, she tackled Rarity and bit down onto her neck, somehow flinging the unicorn away and ripping off some of her flesh. Rainbow spit it out and landed in front of Applejack, leaping at her and causing them both to tumble a few feet across the ground. Rainbow quickly checked if the seeing tool was still strapped down under her wing.

She checked the symbol on her hoof and it was still glowing. It rarely did this while she was trying to fight someone. She quickly shrugged it off, for nothing bad had ever happened during this. She pinned Applejack down and immediately could smell something burning. She removed her left hoof and yelped, falling off of Applejack. Applejack got back up, trying to avoid putting any weight onto her broken hoof. She looked down at her other hoof and screeched out. The edges of her skin and the exposed flesh inside were quickly burning away. She quickly ran away and Rainbow Dash looked down at the bottom of her left hoof and sighed.

"Sweet Celestia," she muttered, getting up. She blew off some of the ash on her hoof before running after Twilight and Pinkie.

"TWILIGHT! PINKIE!" Rainbow Dash called, trotting through the halls of the mansion, trying to find her friends. As soon as she put her right hoof down after a few more steps, the symbol engraved on that hoof began to glow a faint red. Rainbow noticed this and looked down at the ground, lifting her hoof. She wiped some of the dust off the floor but there was nothing there. She grabbed the seeing tool and opened it up, looking at the floor. As soon as she registered what was in invisible ink, she flinched.

𝓢𝓸𝓻𝓻𝔂, 𝓡𝓪𝓲𝓷𝓫𝓸𝔀 𝓓𝓪𝓼𝓱. 𝓑𝓾𝓽 𝓽𝓱𝓮 𝓟𝓻𝓲𝓷𝓬𝓮𝓼𝓼 𝓸𝓯 𝓕𝓻𝓲𝓮𝓷𝓭𝓼𝓱𝓲𝓹 𝓱𝓪𝓼 𝓹𝓮𝓻𝓲𝓼𝓱𝓮𝓭.

As soon as she finished reading it, the first four words disappeared, replaced by 𝓣𝔀𝓲𝓵𝓲𝓰𝓱𝓽 𝓢𝓹𝓪𝓻𝓴𝓵𝓮. Rainbow Dash quickly put the seeing tool away and ran off, desperate to find Pinkie Pie.

I hope she's okay. Rainbow thought.

"DASHIE!!!" Pinkie screamed, panic shining clearly through her voice as she ran around the floor of the mansion. As she turned a corner, she crashed into the rainbow maned pegasus. Pinkie Pie quickly got up and squealed.

"Rainbow Dash! You're okay!" Pinkie cried, hugging Rainbow Dash.

"Pinkie, calm down! You almost gave me a heart attack!"
"Calm down? I don't want you to die too!"

There was a growl behind Pinkie Pie and Rainbow Dash lightly threw Pinkie off of her to the side. Rainbow Dash quickly got in front of Pinkie and growled at the monster. It reached out to grab Rainbow Dash, but Rainbow quickly leaped up the monster, her left hoof slightly burning the ink. But somehow, the ink slightly burned but didn't fully catch fire. Rainbow quickly jumped off and waved a hoof in the air ever so slightly. Almost immediately, a sword appeared in her hoof. Rainbow Dash held it sideways in front of her, ready to attack when necessary. The sword began to glow ever so slightly.

The monster turned around and attempted to reach out again. Rainbow Dash quickly moved out of the way, slicing the hand right off, the sword leaving behind a rainbow and inky looking trail. The monster looked at it and growled. Rainbow Dash looked at the hand, slightly disgusted, and flew back in front of Pinkie Pie, making sure she didn't get hurt. Dash heard something coming from behind and leaped over Pinkie, slicing whoever had been coming from behind. Rainbow Dash saw it was Applejack and the earth pony screamed with fury. Rainbow quickly held the sword in her mouth, grabbing Pinkie and running away. As they reached an intersection, Fluttershy tackled Rainbow to the ground. Rainbow quickly turned her head to the side, the tip of her sword leaving a scar on Fluttershy's face. Rainbow shoved her off of her and threw her to the ground, her left hoof burning a small patch of Fluttershy's skin.

Fluttershy whined and tried to free herself, but Rainbow pinned her down. She sighed and got off of Fluttershy. Flutters quickly got up, but before she could run, Dash pierced the sword right through her heart. Fluttershy howled before dropping to the floor, convulsing a bit before she finally stopped moving.

"I would regret this, but the real Fluttershy would never try to kill her friends." Rainbow Dash said, tossing the sword into the air. It disintegrated into rainbow-colored flower petals and she turned towards Pinkie, who had turned away from the scene. Rainbow Dash walked over and put a hoof on Pinkie’s shoulder.

"Come on. Let's go before they come back."

"Are you sure this will work?"
"If you're so unsure, then why are we doing this?"
"If you're so sure, then why are you asking me that?
"Whatever."
"Why are we doing this?"
"You idiot it's because no one should ever exit and tell the tale. Our souls are somehow connected to this place and if anything happens, we are going to DIE."
"That's not what I mean."
"Then what do you mean?"
"Why didn't we just leave these six alone?"
"We thrive on this place and the life of others. but for this whole life thing to work, we must have them die twice, for it makes it stronger. The mansion alone will not work. It also helps the mansion keep anyone from escaping. Understand now?"
"Yes. But I have one more question... why did we let that one pony escape?"

Author's Note

The bottom of this chapter SERIOUSLY doesn't work well with a dark theme d-b.
And just in case you can't read

𝓢𝓸𝓻𝓻𝔂, 𝓡𝓪𝓲𝓷𝓫𝓸𝔀 𝓓𝓪𝓼𝓱. 𝓑𝓾𝓽 𝓽𝓱𝓮 𝓟𝓻𝓲𝓷𝓬𝓮𝓼𝓼 𝓸𝓯 𝓕𝓻𝓲𝓮𝓷𝓭𝓼𝓱𝓲𝓹 𝓱𝓪𝓼 𝓹𝓮𝓻𝓲𝓼𝓱𝓮𝓭.

and

𝓣𝔀𝓲𝓵𝓲𝓰𝓱𝓽 𝓢𝓹𝓪𝓻𝓴𝓵𝓮.

They say "Sorry, Rainbow Dash. But the Princess of Friendship has perished." and "Twilight Sparkle."
