As the three alicorns hovered in a triangle formation facing the entity, they pointed their horns at one another. Celestia started the chain of magic first with her mind focusing on the Tridimensional Spell. It conjured up a ball of yellow light at the tip of her white horn, and shot a laser beam towards her sister. Luna saw the beam and conjured up her own Tridimensional Spell and her blue aura appeared in a spherical shape upon her horn mimicking her sister's spell. Luna's magic shot a beam of light directly at Princess Twilight's horn as the young mare managed to conjure the spell of her own. It took all her strength but she successfully pulled it off on the first go.

A radiant bright light shimmering in shades of blue, yellow, and magenta shone forth from the collaborative spell as it rose up above their heads. The three mares focused all of their energy and attention on the orb of magic and then turned their heads towards the entity. As the mares' eyes turned fully white one by one, a brilliant light show began as they magically tore open a rift into the mass of dark energy from the entity. "AHHHHHHHHH!" The Queen screamed in pain as she became wounded in the process. She looked back to see the three princesses performing the spell. "NOOOOOOO!" She tried to combat against the light magic but something was holding her back, a force of some type. She felt the tear in her energy form grow wider, "AHHHHH!" She screamed again.

Celestia and Twilight began to pull the spell onto their own horns and away from Luna. This allowed the alicorn to become free of controlling the magic sphere. "Ugh.... wha...... Why are you......"

"Ngh... GO LUNA! WE CAN HOLD IT..... GOOOO....." Celestia yelled above the roar of the magic sphere. Luna regained herself as her eyes turned back to normal and the light faded from them. She hesitated but took the chance to catch the open window that she needed.

With a roar of thunder, she entered the fluidic energy that was a hazy dark purple mist. It was as thick as soup inside the entity. She took a moment to adjust to the new atmosphere. Her eyes burned slightly but other than that she could move through it just fine. Smoky mist swirled around her in spirals, she suddenly realized she could walk. A hard surface had formed beneath her hooves but it was invisible to the naked eye. The only way she could tell it was there was by touch and by the sound of her hooves echoing.

The alicorn mare roamed around taking in the sights and sounds of the void. "Lavender!" She began to call the young mare's name through the mist. "Lav! I know you're here!"

"AHHHHHHHH!" Luna suddenly heard high pitch screaming that could only be from the lavender coloured female Pegasus. She heard it coming from her left and turned to race towards the sound. After a few seconds of cantering, the mare found Lavender running around in circles all spooked and flustered, looking in all directions. "WHAT IS THIS... WHERE AM I? WHERE AM I?? HELLOOOOO!!!!! SOMEONE.... ANYONE!" Luna ran up to the young Pegasus mare and tried to calm her down. "Woah... there... Lav.. Lav! It's me, Luna!" Using magic to pull on her tail gently, the pony halted to a dead stop and breathed heavy as she tried to catch her breath to calm down. Looking up she managed to say, "L-Luna?! What are are you doing here... What's going on?"

"You've been corrupted by an evil soul. What do you remember Lav?" She waited by her side while Lavender tried to think back to the las thing she saw. "Hm... well.... I remember the book that Zecora gave me... and.... oh the floating orb of black magic..... what was that by the way...?" She looked up at Luna with confusion. She suddenly remembered her little back cat, "SAPPHIRE WHERE'S SAPPHIRE IS SHE OK?" she looked around frantically but Luna stopped her by placing her hooves on her shoulders. "Don't worry she's safe... I asked my guard Fleet Heart to look after Sapphire, she was happily playing with her armor. The question is... are you ok? What happened?" The night princess sat down on the invisible surface and gave a listening ear to her friend.

Lavender began to tremble once the adrenaline wore off and collapsed to the invisible ground..... she sobbed as reality hit her of where she was. "Oh Luna! It was so scary! The book that Zecora gave me began to levitate in the air magically... dark magic aura came forth from it and filled my entire house! I couldn't see anything for a few moments before the light dimmed enough for me to see an orb rising up out of the pages and it came rushing towards me. Then I guess... inside of me? I don't know....!"

Luna listened carefully and plotted of how she could help the mare escape her prison. "Lav... listen to me. You are trapped inside your mind. I actually used a powerful spell to physically enter your mind so I cannot stay long. If I do, I may become trapped myself and we become a joint mind." She watched as the mare's eyes widened in fear, so she quickly digressed, "Basically, we need to find a way out of here before we become stuck in here."

Outside of the Entity....

"Arghh!! Celestia! I can't hold it much.... longer! NGH!"

"Hang in there Twilight! We must! Or we lose them both!" Princess Celestia knew how much her faithful student must be struggling with the new spell but she herself was also struggling to hold such a large amount of powerful magic in a large spherical orb. Celestia hoped with all her heart that Luna was doing alright inside the massive entity that was still destroying the surrounding structures and landscapes out of pain and frustration. She heard it yelling, "YOU DARE TO APPOSE ME YOU FOOLS! I WILL TAKE YOUR PRESCIOUS RULERS ONE BY ONE, AND THEN I WILL COME AFTER THE REST OF YOU!"

Back inside the Entity.....

Lavender tried to use her magic to find a way out but to her horror, it had been zapped from her. "My... my magic!!" Luna was horrified that her magic had been taken by the Entity. "Oh no... She's a lot stronger than I first thought. We have no time! We need to get out.... now!"

Author's Note

Luna successfully found Lavender but they become trapped inside the entity. It's up to Celestia and Twilight to save the two ponies before the entity engulfs anyone else and becomes too powerful for them to handle!
