Unhappy that her future as a member of the monarchy is denied by Celestia, Sunset Shimmer escapes through Starswirl's mirror into another world, planning to take it over to prove once and for all she was fit to rule. What she didn't expect—besides a species change—was to arrive in a world already conquered.

WARNING: CONTAINS SPOILERS FOR THE WHOLE STORY: TIMELINE

This story is a sequel to Matters of Principle

For as far back as she can remember, Vice Principal Luna has had no choice but to stand by and watch her well-meaning sister get in all sorts of trouble. Now, with supernatural threats appearing from another world, Luna finds herself losing faith in her ability to make any real difference in her students' lives, or Celestia's.

Perhaps a visit to that other world will provide some perspective.

If there are three things Principal Celestia can't stand, it's paperwork, princesses and her past. Unfortunately, the first makes up her job... and she desperately needs the second to help her resolve the last.

This story is a sequel to Arrow 18 Mission Logs: Lone Ranger

In the year 2258, Randolph Edwards, captain of the Arrow 18, was stranded on the planet when Luna saved him from an explosion. Though his life was saved, he had lost his legs, and any chance to get back home any time soon.

After extensive research to ensure the proper parts won't fail, selecting a group to send, and training said group, Global Space Agency has sent a new team to the mysterious geocentric planet and retrieve Captain Edwards.

The Arrow 19, like it's predecessor, is lacking a proper crew count. With the majority of the funding going to making sure the systems didn't cause a catastrophic failure, the funding for a crew was low. Thirteen is far from a proper crew, but it's more than the predecessor had.

It has been 4 1/2 years since Randy last saw another human, and is excited about being able to go home.

This is the unofficial sequel of Arrow 18 Mission Logs: Lone Ranger by AdmiralTigerclaw. In need of cover art.

This story is a sequel to Dresden Gets Schooled

Harry Blackstone Copperfield Dresden's life has been even stranger than usual ever since he first got involved with Equestria. However, after his last adventure sent him to some strange high school dimension, things have finally settled down into something approaching normalcy. Or at least as normal as Harry's life ever gets. His new apprentice Sunset Shimmer is proving to be quite a handful, but Harry has experience with handling headstrong young women.

However, things take a turn for the worse when he learns that a new threat from Equestria has made its way to Earth. And naturally it's up to him to stop the Sirens before they rock the world's foundations.

Crossover with the Dresden Files. Sequel to Forever!

For his first task as the new Winter Knight, Harry must travel to the land of cute little cartoon ponies to stop a plot by the Order of Blackened Denarius that threatens both Earth and Equestria.

Warning: Includes massive spoilers for the Dresden Files series up through Ghost Story.

This story is a sequel to My Little Denarians

A year has passed since Harry Dresden, wizard-for-hire and Winter Knight, rescued Equestria and the Elements of Harmony from the clutch of the Denarians. Why wouldn't he jump at the chance to return to Equestria to visit his (very) colorful friends in a totally peaceful and uneventful vacation?

Because he's Harry Dresden, and life rarely lets things go so smoothly for him, when it's not killing him to death. And when things go wrong this time, Harry finds himself in a realm far, far more terrifying than Arctis Tor, Discord's realm, or the Outside:

High school.

Follow-up to "My Little Denarians."

This story is a sequel to Why No One Messes With Luna

Shepard has done the impossible. Old foes have set aside their differences, new friends have come into the fold, and the galaxy is more united than ever before. But the Reapers care not for the new alliances they face; they will fall, as countless civilizations before them fell. It is inevitable.

There is still hope. The Crucible, source of unimaginable power, has been constructed by the allies. With this new source of hope in tow, the allied fleets break through the Earth blockade and attempt to use this newfound weapon in a last, desperate attempt to defeat the Reapers and save the galaxy as we know it. Fleets of all races, soldiers of every kind, are united in this final stand.

Equestria, too, has sent what they can to aid in this final battle. Or rather, who, they can.

The Reapers have no idea what they have unleashed.

Warning: This story contains spoilers for ME3 and takes place during the ending of the series. This story is less approachable than the previous stories and may be confusing to those who are unfamiliar with the ME3 ending
