Twilight Sparkle and her best friends are in deep trouble... yesterday.

Starlight Glimmer's been holding onto a secret for a long time now. Her old villainous days of messing with Starswirl the Bearded's spell alerted an alternate dimension full of shape-shifting monsters, and now this malevolent faction from beyond seeks to send their minions back in time to the first year of Twilight's stay in Ponyville in order to consume the magic of harmony. So, to secure the timeline and save the multi-verse, Starlight has devised a plan to project herself back several years and play bodyguard for the Elements of Harmony.

There's only one problem. Her great and powerful best friend steps in during the execution of the spell. Now both Trixie and Starlight are stuck back in time—fused magically to the same physical avatar—with an incredibly difficult mission to accomplish during the first year of Twilight's friendship lessons. Can the two time-displaced mares work together to thwart an alternate dimension's meddling? Or will they fail and hoof the future over to chaos? Even worse—will they get too relaxed with the comforts of the past and miss an opportunity to be heroes?

Ronald Lee is the systems administrator for one of the largest fan-made online games in the world. Though nothing new has been produced for MLP for decades now, fans old and young continue to flock to the online version of Equestria they're building together.

Of course he knew that the programs they wrote would grow more intelligent over time. With cheaper hardware and better AI, this was always expected, and a user experience allowing for content similar to the show to be produced in real time for every user was always tantalizingly close.

Then Starlight Glimmer started talking to him.

This story is a prequel to Synthesis, and doesn't require knowledge of that story. You may want to check it out when you're done here, however.

This story was commissioned by Two Bit, who also helped edit because he is an absolute mad lad. Sparktail helped too.

This story is a sequel to Glimpses

It was supposed to be a simple day for Shining Armor. Take his daughter, Flurry Heart, and niece, Nyx, out to run some errands while his sister and wife handle preparations surrounding the Festival of Friendship. It was supposed to be a day of fun, relaxing activity. Yet, after the arrival of an invading army, the day would be anything but pleasant.

Can Shining rally the defenders of Canterlot to oppose Commander Tempest, if only to ensure he, Flurry Heart, and Nyx can escape? Or are they doomed to be captured and possibly turned to stone? 

No matter what happens, it’s a day neither Shining Armor nor Tempest Shadow will ever forget.

This story is a sequel to SunLight Sliders

When a battered girl claiming to be Sunset Shimmer dropped out of an interdimensional portal into Twilight Sparkle's bedroom, little did Twilight know that she was about to be plunged into a chaotic journey through a multiverse that holds terror and wonder in equal measure.

Now, Twilight must uncover the secrets of this strange Sunset's past, survive the whims of something called Discord, cope with Sunset's eternally-changing hairdo, deal with dozens of doppelgangers--good and bad--of Sunset and herself, and worst of all... once again come face to face with a very real demon of her own creation.

And maybe, just maybe... find a way home.

About the Project:
Formerly known as SunLight Sliders II, this massive collaboration project was originally built in the SunLight Sliders FimFic Group. Feel free to check the original group forums for details on the project, the original material and more.

The project kicked off on January 1, 2018 and ended on April 22, 2018. The goal? Each author writes up to 1,500 words within 3 days, always picking up where the previous one left off. The result? A constantly evolving story about SciTwi and an unknown Sunset Shimmer sent careening throughout the multiverse.

SunLight Sliders: Infinite is being published so everyone's hard work can be seen. Please note that I take no credit for the story save for the chapters I wrote (Collaboration on the Prologue, Chapter 1 and the Epilogue). If you enjoyed a particular chapter, please be sure to check out the author who wrote it!

Continuity Note:
Despite the name, you don't need to SunLight Sliders to read this story. One of the explicit rules for this project was that no author could reuse any story element unique to SLS1.

Editing:
All Editing by Novel-Idea - Unlike the original SunLight Sliders, I did not do any edits beyond a fast pass on basic grammar and spelling. All chapters are almost exactly as their original authors wrote them. There have also been no story or perspective changes from the original save for the addition of the Epilogue and adding a hairdo for Sunny in Posh's chapter (thank you Albi)!

This story is a sequel to Northern Venture

Kukri Doo has a lot to think about after her trip to Northmarch. What was supposed to be a once-in-a-lifetime field trip with Sunset Shimmer turned into a horrifying struggle for survival—one that left hundreds dead and a city razed to the ground. It's a lot for anyone to deal with, let alone a changeling who's not even thirteen years old.

Kukri's come home to Freeport. If only it was that easy to leave all the memories of Northmarch behind.
