The Fall Formal sees Sunset Shimmer defeated and dethroned as leader of Canterlot High School. Desperate for redemption, she lacks anyone to turn to for help - except the five girls who's lives she tormented. Does she deserve help? Does she deserve friendship? Rainbow Dash seems to think so.

Meanwhile, Time Turner, a teacher at Canterlot High School, watches Sunset's progress from afar. But he too is desperate for redemption - but for what? Who has he hurt, and why? How is his story connected to Sunset's?

SF (canon species only; no humans) Ponies were magically and genetically engineered to be the perfect servitor race. They are powerful, adaptable, intelligent and completely under the control of their creators. A laboratory accident frees one such pony from her mental chains, but how can one mare save herself and the rest of her kind if she doesn't even know she's a slave?
This is not the Equestria you know and these are not your little ponies... not yet, anyway.

(Please Note: This story was started before any season three information was available. All episodes in season three and later are non-canon for this story, which also means there's no Crystal Empire in this one. In addition, the promotional map released close to the beginning of season three was also not available and is not compatible with this story. While the OC tag is active because there are OCs in the story, they're really just supporting characters. The focus is on Twilight.)

Also be sure to check out the Rites of Ascension Expanded Universe Group! We're working to develop the resources needed for other authors to try their hand at writing stories set in the Rites Universe!

The Book Two cover art was created by the amazing Silfoe! The original cover art can still be found at Violet Squiggle's deviantArt page.

It is the year 2038, and the Earth is slowly being consumed by a space-borne monstrosity dubbed the Black Tide, which is using nanotechnology to remake the planet into something hideously alien.

Erin Olsen works for Project Harmonics, humanity's last-ditch effort to find a new world before the Tide can wipe them out. But when that world is found, and it turns out to be occupied, Erin will need to find the courage to face the unknown in order to save the inhabitants of both worlds.

This story is a sequel to Upheaval: Breaking Point

Following the events of Breaking Point, Twilight Sparkle and her friends discover that Equestria's demise may not come from an enemy invasion, but from within. The Barrier Lands and the Heartland begin the slow and uneasy process of reuniting into a single Equestria, but this long-delayed joining is already in danger at its conception.

With Celestia's power in her grasp and her agents by her side, the wheels of Black Rose's plans for Equestria's future continue to turn. However, her brazen gamble has done more than just bring down a centuries-old barrier. Ancient powers begin to stir: the remnants of a dark period in Equestria's history, the immortal inhabitants of Celestia's homeworld, and a rising tide of darkness coming ever closer.

Every pony in Equestria knows the names Octavia Philharmonica and Vinyl Scratch. Every musician in Equestria knows and reveres their talent and most semi-jokingly complain that Octavia and Vinyl's relationship should count as a monopoly on musical talent. Very few know their early story, years ago when Octavia had only just left Canterlot Conservatory and Vinyl was... well, being Vinyl.
