The next day, Sun, The Shadowbolt girls, Gloriosa, and Juniper meet at the Mall's food court. Of course, they arrive around the time the mall and the food court is supposed to be open. They grab themselves some breakfast so they can come up with a plan.
"Alright girls, nine detectives, tracking down every student and faculty of Canterlot High that are possible suspect, and only one Memory Stone. Seems impossible, but so does pulling a rabbit out of at hat. And I do that all the time," Trixie says. Then leans back on her chair.
"Trixie, does anyone ever tell you that you talk a little too much?" Lemon questions.
Trixie rolls her eyes, and ignores Lemon's question.
Instead she opens her notebook and brings out a pen, "Let's talk about motive."
"We don't even know the motive," Juniper says.
"True, but we know what the objective is. Someone is trying to separate Sun from her friends. The girls remember they are friends with each other, but don't remember Sun begin a part of their group. Meaning, someone is trying to separate Sun from the others," Sugarcoat explains.
"But then why erase everyone else's memories?" Indigo asks.
"Whoever did it probably has too. It will seem strange that me and the girls are the only ones who have tampered memories," Sun suspects.
"But still, we got until tomorrow evening to find the stone before all the memories you and the girls had will be gone forever," Gloriosa says with concern.
"Then let's start searching," Juniper says.
After having lunch, the girls split up into three groups of three people. Sun goes with Gloriosa and Sugarcoat. Trixie, Lemon Zest, and Jupiter are another. Finally, Sour, Sunny, and Indigo are a third team. Each of the girls are looking around town to see if anyone knows about the stone. Luckily, Sun and Trixie have their recent yearbooks so they can keep track on the students and faculty they talk to.
Trixie's group run into Microchip who is in the electronics store.
Trixie firmly says, "Alright Microchips, word says that you know about erasing memories."
"I erased a tone of memories this morning," Microchips replies.
"Really?" Juniper questions.
"You did?!" Trixie adds in surprise.
Microchips nod his head, and brings out his phone.
He explains, "Four terabytes of quantel-accelerflex memory to be precise."
The girls realizes that he is not the one they're looking for.
"Lame?" Lemone mumbles.
The the three girls take their leave.
"How come no one's ever impressed by that?" Micro asks himself.
Sunny Flare and the others talk to Principal Celestia and Vice Principal Luna.
"I'm sorry, but my sister and I don't know about this Memory Stone you're trying to seek or anyone who might have it," Luna says.
"But it does seem that another magic problem is happening in this world," Celestia says.
"Seems like it," Indigo replies.
"We wish you all the best of luck," Celeste says.
"Thanks," Sour says.
Finally, Sun and her group are talking to Maud, Pinkie's older sister. Sun gives Maud the picture of the memory stone.
"Is there anything you can tell us about it? Anything at all?" Sun asks.
With a deadpan look, Maud answers, "I can't tell much from a drawing."
Sun sadly sighs, and says, "Okay."
She takes the picture from Maud and put it back in her bag
But Maud says in a deadpan voice, "Only that it's felsic-intrusive igneous, granular in texture, most likely arranged in an equigranular matrix, with scattered biotite mica and amphibole, at least sixty-five percent alkali feldspar by volume, with a melting point of twelve-fifty centigrade, plus or minus ten degrees. Sorry I couldn't be more helpful."
Sun and the others are confused and disturbed on Maud's knowledge that they slowly walk away as she talks.
The girls have been searching for the stone all day, but is unable to find anything. So far, they manage to ask half of the people because they are unable to find them or others are not even in town. They search until late in the evening, and call it a day until tomorrow, and agree to meet at Sun's house the following morning.
Early the next day in Equestria, Princess Twilight and the others have search for the last page of the scroll or anything that can help get Sun and the girls' memories back. Few days ago, Sun explains that some people never has their memories erased and that those at CHS seems to have. Princess Twilight and the others search and search for a clue, but they found nothing.
"We've looked everywhere! Why can't I find the missing pages?" Princess Twilight asks in a panic.
Then she screams as she jumps in the air with her wings spread out frantically moving her front hooves, "I've always been good to you, library!"
Then had her face slam on the desk, causing the chest to fall and break. The others look to see the chest lid has broken off.
"What's that?" Falling Star asks, noticing a piece of paper sticking out of the eye of the carved face.
Realizing what it is, Princess Twilight gaps in relief, "This is it! The last piece was in a secret compartment!"
"That's great. Finally we're getting somewhere." Falling Star says.
Stygian asks, "What does it say?"
Princess Twilight reads the scroll, but exclaims in shock, Clover the Clever buried the Stone!"
"What?!" Falling Star exclaims.
The others look at the last piece of the scroll. They see the memories stone is in the middle of three rocks that form a triangular formation.
"This rock formation must be somewhere in the other world," Starswirl says.
"Yes. but it doesn't say how to get your memories back," Princess Twilight says.
"That's right, Clover wasn't able to destroy it, but was able to hide it in the other world," Falling Star adds.
"We must get this information to Princess Sun at once," Starswirl says.
Princess Twilight levitates the book she uses to contact Sun. Stygian then look at the back of the scroll and notice something strange.
"Hmm, that's peculiar. There's seem to be something written back here," Stygian says, looking at the back.
Confused, Starswirl looks at the back to see nothing, but there is a strange message on the bottom corner that is not ripped.
"There's a message. It says, "A bright light will tell all." Starswirl reads.
"A bright light?" Falling Star questions.
"I remember that spell. It was so Clover and I can send secret messages to each other. Only a light of a unicorn's magic can reveal the message on scrolls or any message," Starswirl says.
"Which means, Clover had a secret message written on the back. Something that only he know," Princess Twilight says.
"We're going to need some more light," Falling Star says.
Princess Twilight asks Starswirl, "Can you perform the spell."
"I most certainly can," Starswirl answers.
He lights up his horn to create a strong bright light that surrounds the room. With that, a secret message has appeared on the scroll.
The other gasps in shock as the two princesses enter the room to see the message as well.
"This is quite a find. Who would have thought Clover left a secret message," Princess Celestia says.
"Indeed. Clover must have decided to add and extra entry to the scroll that only those can use," Princess Luna adds.
"But, what does it say?" Falling Star asks.
Princess Twilight takes a look at the message. She reads, "
"This must have been the most hardest thing I did in my life. Even though I never want to come at such a decision, but it is the only way to protect everypony from the stone, especially my dear friend Regana. Regana created the Memory Stone with her magic so that ponies can forget her ever having trouble with her weak magic. However, she decided to use dark magic to soon and the Stone was completed…"
"That all it says?" Princess Twilight questions.
Suddenly, Stygian has an idea, "What if the rest of the entry is on the other side of the rest of the scroll?"
"You know, I think you're right," Princess Celestia agrees.
Princess Luna levitates the rest of the scroll, and unroll the whole thing. Soon the rest of the message appears.
Princess Celestia continues, "However, she decided to use dark magic and soon the Stone was completed… but at a terrible price."
"Soon, the Memory Stone became too powerful that not even Regana could control. And then the unthinkable happen, Regana became consumed by her own sadness and anger align with the power of the Memory Stone that she ends up being corrupted by it," Princess Luna adds.
"Corrupted? You mean she was corrupted by the very thing she created?" Falling Star asks in concern and shock.
"It seems so," Princess Luna answers.
Stygian reads, "However, that is not going to stop me from getting my friend back, so I travel land and sea to find her, and free her from the Stone. Sadly, she uses the Memory Stone on me to erase my memories, but I wrote everything down on parchments of paper so I'll know where to go. I have come to discovered that on a third day after a memory has been taken… not only will the memories will be erased forever, but will give the user more power. And thus, Regana became more consumed by the Stone's power as a memory has been taken."
"Oh no!" Princess Twilight quietly exclaims in shock.
Falling Star takes the next entry, "Finally, after a long journey of tracking her, I was able to corner her. However, she used the power of her magic energized by the stone to create a portal and went through it. I went in after her. Soon, I find myself in a strange world, my body changed, and I walked on two legs. Regana has a well."
"Must must when they enter to human world," Princess Celestia suspects.
Princess Twilight takes it from here " I was able to confront Regana and somehow able to use her magic in this world. I may not be able to use my own magic, but I still have the spell book Starswirl gave me that contains powerful magic. Regana was about to use it to erase all my memories, but… didn't do it."
"Regana was trying to fight the Stone's power, but it must have been too much for her," Starswirl says.
Starswirl takes the next entry, Suddenly, I see the real Regana in her eyes, and tears comes down her face. She says, "C-c-clover… help me… I… I can't control myself." I tried to stop Regana but she tries to use the stone on me. Soon the real Regana tries to fight the stone. She soon says her finally plea, "I… I'm sorry… I… I should have… never made that stone… I-I was angry with everyone for hurting me because of my magic… I end up dragging you into this… There's… there's nothing you can do to help. I… I also sorry that I don't know how to destroy the stone that I've created But please… please… grant me one final wish…"
"Final wish?" Falling Star questions.
"Regana wanted Clover to do something before she was taken over by the stone," Starswirl suspects.
"And it seems Regana doesn't know how to destroy the stone she created," Stygian adds.
Princess Twilight reads, "I'm amazed to see Regana is trying to fight for control. I asked her what is her final wish. She was in tears, and still tried to fight control… But… she manages to say is, "Please Clover… if you are able to… if you are able to… Please… imprison me in the Memory Stone and bury it where nopony can find it."
Everyone gasps in shock.
"Im-imprison her?!" Falling Star calmly exclaims in shock.
"It… it can't be," Princess Luna adds.
"As much as I hate to do it to my dear friend, I must do it to protect her and everypony. So I used the spell Starswirl showed me and imprison Regana inside. Seeing the stone, I realized that if anypony touch the stone will be put under its control. So I buried it in the middle of the rock formation where no pony can find. Then I went through the portal and return to my home world. I may have saved everypony from the stone, but I lost a very dear friend. Regana… my best friend… I never saw her again," Princess Twilight continues, and tears begin to fall from her face.
Soon the others' eyes are starting to water as well.
"That… that must have been… so hard for him," Falling Star says.
"Yes. I know too well how Clover felt when I was forced to imprison somepony who was so dear to me," Princess Celestia says.
"I know sister. I know," Princess Luna replies with sadness.
The two sisters then pull each other to a hug.
"It seems that we found out more about the stone. A darker truth behind it's origins," Starswirl says.
"You're right. If what Clover said it's true, then whoever is using the stone now is being corrupted by it," Stygian says.
"And now we know where the stone was buried at. We know now that Sun must destroy the stone before sunset tonight," Princess Twilight adds.
Then Princess Celestia says, "You must warn Sun at once."
Back in the human world, Sun is having the meeting in her bedroom. She also provides some drinks and snacks for them. Of course, they are on a urgent meeting.
"We have until the end of the day to find the stone, but we can't find it. Think Trixie! Think!" Trixie says, feeling frustrated.
"Calm down Trixie, we'll find it. We just need to come up with a new plan," Gloriosa says.
"I thought that if we look over the yearbooks, but couldn't find anything. We practically check most of the people in the book. A to Z," Sun says looking over the book.
Suddenly, Juniper notice something on one of the pages, "Wait! Picture not listed. Wallflower Blush. Who Wallflower?"
"Wallflower is one of my friends, but I don't think she has anything to do with it," Sun says.
"And we still have a few more people to ask," Trixie adds.
"If only we have another lead or something. I can't take much more of this!" Sour screams in aggravation.
"Calm down Sour," Sunny says.
"I am calm!" Sour scolds.
Just then, they hear a vibrating sound and they look to see the book on Sun's desk is glowing and vibrating.
"Why is your book moving?" Lemon asks.
"It must be Princess Twilight. She must have found something," Sun says.
Sun looks in the journal to see the message appearing on the pages. Along with a picture of them Memory Stone and rock formations.
She reads the passage, "
Sun, we believed that the Memory Stone was buried under this rock formation. What's more, we found out more about the Memory Stone. Apparently the stone is so powerful that it can corrupt anyone who is in possession of it, and Clovered was forced to imprison Regana inside. You have to find the stone and destroy it before sundown today. Otherwise, the memories will be erased forever, and whoever has it will be controlled by the stone."
Sun look up to see the girls are stunned to hear the news.
"That's bad is it?" Trixie questions.
"Oh I don't know.." Sour says in a sweet tone.
Then sourly shouts, "Does being controlled by a rock erasing memories sounds good to you?!"
"It's not," Indigo replies.
"But it seems Princess Twilight know where the stone was," Juniper replies.
"Yeah. The rock formation. Where are we going to find something like that?" Sunny asks.
"It seems that we're close to nothing at this point," Sugarcoat says.
"No. I.. I think I've seen this before," Sun says, looking at the rock formation on the page.
Sun takes a closer look at the rock. Suddenly, it hit her. She grabs one of her photo albums and look through the pages. Then she manages to find what she is looking for. It's a picture of her and Wallflower, and with the completed garden. Sun looks at the two and realizes the pictures are a match.
"It… it can't be…" Sun says in shock.
Sun quickly gets up, and says to the others, "We need to get going now!"
"Why?" Lemon asks.
"Did you find something?" Trixie asks.
"Yes. I did. And… if my suspicions are right… then my friend Wallflower is in big trouble," Sun says looking serious and worried.
Now she knows who has the Memory Stone and is in serious trouble by it.
