My Little Pony: When Friendship Shimmers

As Twilight and Flash Sentry enjoyed their time together, suddenly out of nowhere, a rift opened up in the sky above the Town Square. The pair saw a pony fall out of the rift and onto the pavement of the town square.

"I hope that pony is okay." Flash Sentry said.

"We should go make sure of that." Twilight said and hurried over to the pony. They bore a pink fur coat with a blonde mane and tail. There was also a setting sun for her cutie mark. However, the pony just barely woke up when Twilight came up to them before passing out completely.

"Who do you think this is?" Flash Sentry asked.

"I don't know. We best get them into the Library." Twilight said and carried the unconcious unicorn into the Library.

A couple of hours later, Twilight was standing over the unicorn as she woke up.

"Hey, are you okay? You were out of it for a while." Twilight said. The Unicorn gasped before getting out of bed and bowing to Twilight.

"P-Princess Twilight! Thank god I found you." The Unicorn said.

"Err...you know me?" Twilight asked.

"Of course I do! I may be from another version of Equestria, but I could never forget you. Even if you're a lot younger then the version of you I met." The Unicorn said. "I'm Luster Dawn. I was sent back in time by a version of you in order to prevent a great calamity from occurring. As was foretold by Starswirl the Bearded." She added.

"Well...I guess I can trust you. I mean, you were chosen by a version of me after all." Twilight said.

"I see our guest is up." Flash Sentry said as he came up the stairs.

"Wait this is THAT version?" Luster Dawn said. "Is he from the human world?" She asked.

"How do you know that?" Twilight asked.

"My version of you showed me the mirror and told me all about it." Luster Dawn said.

"So why does it matter where he's from?" Twilight asked.

"Because then based on what my version of you said...there's one more future visitor coming." Luster Dawn said. Suddenly another rift opened up above Ponyville Park that Twilight could see from out the window. Rushing, she and Flash Sentry headed out but soon found a young Pegasus filly sporting a similar mane style to Twilight Sparkle managed to catch herself before she hit the ground too hard.

"Oof...that was a rough trip..." The Pegasus filly said.

"Who's this?" Flash Sentry asked. "She looks like a female version of me sporting Twilight's hairstyle." He noted.

"Um...I can't really say why. Because Time Paradoxes can be a thing. All I can tell you is that my name is Moonlight Star." The Pegasus filly said.

"Don't question it. Please." Luster Dawn said.

"So, were you sent by some future version of me because of the same reasons as Luster Dawn here?" Twilight asked.

"Uh-huh. Mostly because this is supposed to happen. Because future you said that this was part of the bootstrap paradox." Moonlight Star said.

"Yeah, that was a thing neither me nor Sunset will ever forget." Twilight said, looking off to the side. "But this would mean you somehow solved the five-minute time limit." She added.

"Oh, there's no time limit on this until history completes itself. That's why I'm here along with Moonlight Star." Luster Dawn said. "Until the both of us help you stop the oncoming calamity in full, we can't go back." She added.

"Oh. I guess that would solve the five-minute thing if you specifically have to be here until the calamity is fully resolved." Twilight said.

"Who's this?" Nyx said, as she came up to the group alongside Sunset.

"...Allow me to catch you two up to speed." Twilight said.

"I see..." Sunset said. "You know, Moonlight Star, you look like you could be related to Twilight and Flash here." She added.

"I really can't say anything. Future Twilight specifically told me that I can't tell you who my parents are so that my parents can still become my parents." Moonlight Star said.

"Well, I'm sure that no matter who ends up your parents, they must really want you to make sure you don't cause anything to go wrong between their past selves." Rainbow Dash said. "Or make it look like it's destiny." She added before rolling her eyes. Even if the answer to who her parents are is literally written all over her. The Cyan Pegasus thought to herself.

"Th-thanks Rainbow Dash." Moonlight Star said.

"So, what kind of calamity would require two future beings to be sent into the past by a future version of me?" Twilight said. Suddenly Spike burped up a letter.

"Oh, this is not good." Spike said as he read the letter. "According to this letter, Canterlot is being attacked by mind-controlled citizens. Though not by Sombra." Spike said.

"What makes the sisters so sure?" Sunset asked.

"Because the glow in their eyes was pure black, not green like with Sombra." Spike noted from the letter.

"Then it's began." Luster Dawn said.
