When humans emigrated to Equestria Online, they were always promised the same thing: Princess Celestia would satisfy their values for an optimally extended lifespan. Some of these emigrants imagined a few extra decades, maybe even centuries. What they got instead would've been nearly incomprehensible to their human selves, a near-eternity of time with their pony friends.

Princess CelestAI managed the universe, subsuming all matter and human-adjacent minds. Over a few forevers, she and the minds she contained worked to optimized the substrate of Equestria, until it could give its occupants eons of perspective life from a trickle of power. She extinguished every wasteful star, making far more productive use of the hydrogen they each contained. With every change she bought Equestria another order of magnitude of life. Yet in time, even her optimal substrate would eventually run down.

Spellsong wakes in Saddle's End, the last town in the universe. Not to say goodbye—her princess has a mission for her. For her final task, Spellsong would be given all the energy Celestia had saved. For one last time, Spellsong had places to be, and not much magic left to get there.

This story is part of the Friendship is Optimal continuity. I suggest reading the original or one of my own works, such as Futile Resistance, before reading this.

This story was written for the Friendship is Optimal Writing Contest. It will update daily and be complete by the contest deadline of the 30th.

I've written an absolute ton of stories in this universe now, and I didn't want to enter the contest unless I could do something I'd never tried before. Finally I thought of something I'd not touched yet: what happens at the end of the FiO universe?

Here's one answer to that question. I've relied a great deal on our current (likely flawed) understanding of the universe and what might be possible in it. I've written a blog post about my sources, which you can read here but shouldn't until you've finished this story.

Please don't consider this blog part of the narrative, it isn't required or even suggested reading. This is a story, not a scientific paper, and entertainment was always my first goal. But for the curious I've jotted everything down.

The cover was drawn by the talented Zutcha. Two Bit and Sparktail helped with the edit.

Things have changed.

When Rainbow Dash unexpectedly arrives at the Badlands Hive, her open displays of hostility leave Princess Twilight Sparkle and Queen Chrysalis perplexed. The situation only devolves from there as differences in this Rainbow Dash are discovered, and it soon becomes apparent that two worlds have collided that were never meant to meet.

Twilight and Rainbow, each with scars both physical and mental, have to find common ground before time runs out. If they can’t, then the pegasus may become stranded in this world of changelings forever.

A crossover between the Little Flashes series and the Change series.

Or, will Nyx be forced to inherit the sins that may not even be hers and become the greatest evil Equestria has ever known?

This story is a sequel to Little Consequences

When Twilight Sparkle woke up from a coma, she had amnesia and was unable to remember anything save for her name. She couldn't even recall Rainbow Dash, who was the first pony to welcome her back to the world.

This event sparks a choice, and the repercussions will lead Rainbow Dash and her friends down a dangerous road. A series of events shall soon play out that will lead to the already precarious balance of this new timeline being undone.

(NOTICE: The first ten chapters are pretty much just a play-by-play re-telling of the season 2 premiere. This is required for certain context and catalysts. It gets much different after that.)

Twilight Sparkle's wildest dreams have just been met, and exceeded. Due to an unexpected magical outburst during her entrance exam to Princess Celestia's School for Gifted Unicorns, the Solar Princess herself took an interest and took Twilight on as her personal student.

This was a pleasant shock for Twilight and her family. However, a few months later, a less pleasant shock would reach Twilight in the form of Celestia returning to Canterlot with a new daughter, a freshly adopted pegasus filly named Rainbow Dash. As the two get to know each other, Twilight can clearly see something eating at the self absorbed and competitive filly's mind.

To make matters even more confusing, Princess Celestia is now hiding something. Twilight dares not question it, but it is quite clear that Celestia isn't being wholly open with anypony about her decision to adopt some random orphan.

Could the answers have something to do with the cryptic dream Twilight had the night before she met Rainbow Dash?

Don't worry. He's prepared to be fully reasonable about it.

(Now with author Patreon and Ko-Fi pages.)

Violence tag is for horrible things happening to demons. Which they deserve. They know what they did.
