"I think its a bit late to change your mind, Cadance!" Sapphire cried out as she saw the beast taking in a deep breath. Looking up at Luna, Sapphire shouted, "Luna, can you do something about the background? Having some water would be very helpful right now!"
"Yes, I shall craft you an envi—" Luna started to say until the nightmare's scenery changed as the alicorns were surrounded by ruined buildings, a sky made out of broken mirrors now appearing above them.
"Luna, th—" Sapphire was about to say until she saw the beast reaching out with a claw, only for a large fireball to hit the claw, sending it away as the beast roared in pain.
Looking at the source, Sapphire saw Celestia had taken to the air, her horn alight with her magic as she looked upon Sapphire and Cadance as she cried out, "You two, don't just stand around! Keep moving so you're not a target!"
Luna grunted in annoyance while looking at the sky as she stated, "Sapphire, you must make due with the current area. Whatever these mirrors are, they're preventing me from altering the scenery to your advantage. For now, I can't aid any of you, for I must keep the nightmare at bay so that you only have the memory. I wish you luck in defeating Mayhem," before she flew high into the sky as Celestia let out another beam of fire on Mayhem, only for it to block the attack with one of its claws before letting out a stream of fire at Celestia.
As Celestia dived to dodge the green flames, Cadance flew up to Sapphire as she asked, "Is that thing really called Mayhem?"
"Yeah, don't know why its called that or if we’ve mistaken it for something else. Right now though, we need to focus on the fight and keep your distance from me!" Sapphire declared as she lit her horn up, feeling out for some water. Detecting some water from below the ground, Sapphire let out a sigh of relief as she started to pull on it before ducking as the monster swung a claw at her. "Horseapples! Why did it have to have such a long reach?"
Getting in front of Mayhem, Celestia erected a barrier of fire before firing a beam of magic at the creature’s head, causing it to roar in anger as it was pushed back. "Sapphire, do you have anything that could restrain this beast?"
"Yeah, just give me a moment and I'll try to grab onto it or slow it down at least," Sapphire replied as she returned her focus to the water she was gathering. Lifting her horn up, Sapphire saw the water being pulled out of the ground, feeling that it was about a pond's worth. "That’ll have to do," Sapphire commented before directing the water onto the monster's lowest set of arms, grabbing onto its wrists as she pulled it down. "That's all I can do for now!" Sapphire cried out towards Celestia.
"Even the smallest of things can determine whether we achieve victory or defeat," Celestia stated as she lit herself on fire and charged past the barrier and onto Mayhem, whose jaw was open until Celestia slammed onto the top of it, closing it shut.
"Alright, I'll t—" Sapphire started to say, until a voice that sounded familiar reached her ears, silencing her as she turned her head towards the source. Upon finding the source, she saw the stallion that she assumed to be her father, looking surprise as a rather large wall was falling on top of him.
"Daddy!" cried out a voice that Sapphire recognized as her filly self as she saw her crying in her mother's forelegs while she was flying low to the ground.
"No..." Sapphire muttered out in horror as the sounds of battle was starting to fade away, despite Celestia’s war cry or Cadance’s attempts to get Sapphire's attention. Following the pair, Sapphire started to see what looked to be shadows of other ponies, running away from fear. Glancing at the rubble that was the wall, Sapphire felt a pang of loss as tears rolled down her eyes, making her realize that the stallion didn't survive.
Returning her attention to her mother and her younger self, Sapphire followed the pair from the sky, watching as her mother darted one way and another as the shadows started to scatter. However, Sapphire noticed that the shadows weren't running about in a panic like the residents of Ponyville did when the Ursa Minor attacked, but rather they were spreading out as they were heading in one general direction before disappearing from her sight. "This... these ponies are running away from something... like we were just attacked," Sapphire muttered out before returning her attention to her mother, only to see that her pegasus teacher Rift was flying near her.
"Rift! What is happening?" cried out Sapphire's mother as she held the sobbing filly against her chest.
"It's Mayhem! It came out from beneath the ground with its spawn! We must have wandered into one of the areas that Gluttony's spawn once dug through!" Rift cried out as he spotted something in the sky. "Look out!" Rift cried out as he flew higher, swinging the poleaxe he always seemed to have on his side at what looked to be a portion of a building. The blow shattered it as what looked to be a gust of wind come out of the blade of his weapon.
Looking at the sky in fear for a moment, Sapphire's mother returned her attention to what was in front of her, before a mare cried out, "Cresent, Look out!" Turning around, revealing that she was the one called Cresent, Sapphire's mother saw a stone column coming straight at her.
As Cresent realized that the column was too close for her to dodge, she threw the younger Sapphire out of her forelegs while screaming, "Somepony, save my daughter!" before she cried out in pain as the column crashed into her back. All the while, Sapphire just watched on, more tears flowing down her face as she looked at the scene with utmost horror, knowing that she couldn't do a thing to change the memory.
"Mommy!" the younger Sapphire cried out, only for Runic to appear, catching the filly with one of his forelegs. Sapphire then shifted her attention to her mother, seeing that the column was on top of her, pinning her down. Runic lit his horn up with a violet glow, until the ground shuddered, causing him to lose his balance. Hearing a familiar roar, Sapphire turned to see Mayhem climbing over a wall, much to the horror of the memory shades at her side.
"Runic, just go!" Cresent shouted, looking into the younger Sapphire's eyes as the filly was bawling out for her mother as Mayhem started to take a breath.
"Mommy! No!" the filly cried out as Runic started to cast a teleport spell, but before he could finish casting it, Mayhem let out a stream of green fire at them, the fire consuming Cresent as she screamed in pain. Suddenly, the memory ended right when Runic finished his teleport, yet Sapphire herself just stood there, staring at the spot where her mother was last.
"I... I saw my parents... die when I was a filly..." Sapphire muttered to herself, tears coming out of her eyes in full force. As she felt like she was about to collapse, she heard the memory Mayhem letting out another roar, drawing her attention towards it as she stared at it, watching as Celestia was circling its head while hitting it with an intense beam of light while her body was alight with fire. Cadance herself was fighting behind a light blue barrier of magic as she was off at the side, using her magic to tear a building down on the creature's tail and side, covering it with debris as it let out a roar of fury.
Staring at the scene for a moment, Sapphire started to feel her sorrow giving way to anger, an anger that soon grew to a fury. Leaping into the air, Sapphire roared in rage as she flew straight at the beast, her horn alight with her magic as she tugged at any sources of water that she could feel. Pulling the water out from beneath them, Cadance and Celestia backed away as they saw a massive surge of water coming out of the ground, so much that Cadance thought it could flood a small town on its own. Lifting her forehooves up, Sapphire then slammed them together, bringing the water to crash into Mayhem from both sides before freezing.
"This is our chance! Sapphire has the monster contained," Celestia stated as she took to the air, firing a beam of golden energy onto Mayhem's head, causing it to roar in pain.
Cadance drifted to the side as she looked for an opening of her own, before noticing that the ice is contracting around the beast, causing her to comment, "Okay... I don't know what Sapphire did when she ran off on her own... but note to self, don't make her angry..."
"Die already, you moon cursed beast!" Sapphire roared in her fury as she pulled even more water from the dreamscape before compacting it as she slammed it into the monster's face.
"...And keep some cakes in reserve," Cadance stated to herself before shooting a beam at one of Mayhem's shoulders.
Firing one more beam at the monster's head, Celestia flew over to Sapphire, where she then said, "Sapphire, can you hit it with all your power from the front while I do the same from the back? It might be enough to bring an end to this being."
Briefly glancing at Celestia, Sapphire replied, "If it will kill this monster, then do it!" as she pulled her forehooves back, pulling as much water away from the beast while keeping it in her hold, as she gathered it into a cone of water before shaping it into the form of a drill bit as she compacted the water further. Meanwhile, Celestia flew by Cadance, saying, "Help Sapphire hold it down so it can't escape our attack," before flying to some distance behind Mayhem. Lighting her horn up, Celestia's eyes start to glow as her body started to give off a light glow. Watching her two fellow alicorns preparing an attack, Cadance noticed that Sapphire's icy grip on Mayhem was starting to crack, causing her to light her horn, wrapping her magic around the icy prison as she tried to hold it together.
"Cadance, get out of the way now!" Sapphire stated as she got behind her frozen drill, using her magic to spin it as she used her magic to launch the drill at Mayhem. Seeing Sapphire making her move, Celestia suddenly engulf her body in a sphere of burning plasma before charging at Mayhem's back. Sapphire's drill was the first to hit, impacting the beast in the chest as it sent it backward, shattering its icy prison. However, before it could fall onto its back, Celestia struck it, trapping it between the two attacks as Sapphire kept the icy drill's rotation going, causing it to roar in pain. Eventually, the drill finally pierced through its armored hide, allowing it to go through the monster as it burst out of its back, narrowly missing Celestia as she dodged to the side.
"Well... that was easier than expected," Cadance panted as the monster fell onto its back as Celestia's spell ended but Sapphire's drill continued to push forward, drilling into the ground until Sapphire finally dropped her forelegs. Panting in satisfaction of the corpse of one that was responsible for the death of her parents, Sapphire raised her head as she cried out her rage and sorrow, causing the mirrors to crack before shattering to bits, revealing a nighttime sky that had a blue moon that was larger than Luna's own moon with a smaller yellow moon by its side.
The sight of the sky caused all the alicorns to stare at it in surprise, until Luna, who was off on her own still as she commented, "So... Sapphire was referencing two moons..."
