Memories of a time long gone by hold the key to Luna's salvation. To save her sister, Celestia sends Twilight on a quest through Luna's mind, searching for the source of an ancient spell that is slowly killing her. What she finds may change her forever.

Twilight experiences Luna's life first hand on an emotional journey through the dark alicorn's past.

Twilight's Research into Divination magic has given Rarity a vision about her future love. Will she interpret the portents correctly?

The star system Omega Centauri was just another oddity on a map to scientists in the not too distant future. However when they found the star was orbiting an earth-sized, earth-like planet instead of a black hole as its motion had suggested, a mission was scrambled to investigate this most unusual of celestial behaviors.

Hamstrung by politics, and nearly crippled before it began, the 'Lone Ranger' mission was reduced to just one crew member and left to his own devices.

These are the logs of Arrow 18 and its lone commander. This information is classified TOP SECRET by the Global Space Agency.

Do NOT tell the princess.

When Rainbow Dash crashes into an impromptu sleepover at Twilight's library, the unicorn seems to be acting strangely, though Dash doesn't think too much of it. As usual, the pegasus has little thought for the feelings of those around her. Some ponies are just oblivious.

War is approaching Equestria and the Celestial sisters' ponydom is doomed to fall. So Luna and Celestia must travel to the capital of the ponysty ruled by the dark sovereign empress Nightmare Moon, in an attempt to avoid a war that they can never hope to survive. But upon their arrival the empress forces them into a dynastic marriage, or else she'll destroy their ponydom and enslave all of their subjects.

The Elements of Harmony are defeated and Nightmare Moon stands on Equestria's throne as their new Queen. Is Equestria doomed to suffer through night time eternal or will they be... perfectly fine? Twilight finds her new job as slave or "personal assistant" to her new ruler to be a bit maddening. But is this evil sarcastic queen really as bad as she originally believed? And just how many others are diabolical enough to cash in on the change in staff? Can Nightmare truly run a peaceful Equestria? Let me just answer all these questions right here in the description...

Discord waits alone and forgotten in the Canterlot gardens, brooding over his hatred for the princess and wondering who truly was the monster between them. But an unlikely visit one night changes him and his feelings for Celestia...

Love doesn't always find a way.

Note: I am aware that this is poorly written. You're probably better off just skipping this and reading The Three Notes, which is slightly better and stands well enough on its own.

After visiting the past in It's About Time, Twilight spends some quality time with Princess Celestia before returning to Ponyville. She then falls into a coma and wakes up where no living pony would ever wish to be, and things only get more complicated when Celestia gets an unexpected visit from herself. Featuring Twilight, Celestia, Luna, The Underworld, and some other alicorn etc.

The Princesses find an alien creature barely clinging to life at the scene of a terrifying crash. Can the Combined Power of the Elements of Harmony save it, or more importantly, should they save it? Will the arrival of this strange creature tear Equestria apart?
