A horrible Cataclysm has turned all of Equestria into a Wasteland of barren ash and twilight desolation. The Sun and the Moon have been destroyed. Everypony has died--including Princesses Luna and Celestia. But one pony miraculously survives; she is a lone wanderer, the last of her kind, surrounded by menacing creatures that hate her. She navigates the Wastes in an airship and scavenges off the blighted landscape to keep herself alive.

Then one day she meets an old companion who grants her a gift, the chance to go back in time to the warm and sunny days of Ponyville, where her dead friends live in happiness. How far will the last pony venture into this joyous age of Equestria, even if she fully knows that there is no way to change the horrible fate of everypony she loves?

Making friends is hard. Seethe, a 17 year old boy has made this discovery after getting bullied by almost everyone in his school. It got worse when they found out he was a brony. Things got really weird when he answered his door to see a girl asking for help. Join Seethe as he tries to help the main six get back into their world, find out why they came, and see his life as a living hell. (This is my first FIMfic, feedback is greatly acceptable. Please feel free to say what you liked, didnt liked, ect. and thank you for reading.)

We all wear a mask called composure, beneath which hides a heart that twists with guilt and hidden feelings. Regal as she is, Princess Celestia is no exception. What might be revealed should circumstances cause this mask to slip - or break?

Set several years after the potential conclusion to the series.

Discord is once again loose, but after using his randomness to find some interesting information on some strange phenomenon in another world that has to do with an island and a bunch of humiliating events, the crazy spirit of disharmony and chaos comes up with a new, sick, twisted, disturbing plan that involves capturing 20 of the most popular ponies (and three non-ponies) and forcing them to play a new game while the rest of Equestria watches in horror (or most likely secret amusement and possibly envy of not being picked themselves).

What does the rotten host Discord have in mind for our 20 unfortunate selections? Well, looks like you'll have to wait and find out! Maybe, just maybe, if Discord is feeling generous, the winner of his new "game" will get a grand prize. Everyone pick a character to root for and let's get it on!
