You know what they say once you hit rock bottom...

Comet takes his job too seriously. Angel doesn't take anything seriously.

Acid, a threat to all of Equestria looms over the land seeking to destroy the world as he pleases. It seems Sin is the only Changeling possibly strong enough to defeat him. With no signs of other Evolvers around, will this distraught mare be able to cope with the maddening effects of solitude?

Edit: Due to complications with the ongoing story - no direction for it to go off of - it has been cancelled.

The Cutie Mark Crusaders have always lived in the now, getting what they think needs to be done as a soon as possible, executing their plans just so they can move on to the next one right away, not thinking about the consequences till they’re right there in their faces. But when an attempt to earn their cutie marks goes too far, Sweetie Belle and her friends must face a horrible reality that sends their world into darkness and fear. How will the truth be uncovered and what will be sacrificed to undo this nightmare?

When Princess Celestia faces a harsh choice to execute an innocent and virtually harmless changeling, will she be able to go through with the notion of taking the filly's life, or will sympathy overtake her moral alignment?

Just about everypony in Ponyville knows Scootaloo. She's your normal, carefree pegasus foal who crusades for her cutie mark, zips around town on her scooter, and looks up to her idol Rainbow Dash. But what if that's not all there is to her? Scootaloo worries that her friends will find out that she's not the foal they know and love, or that she's not even a foal at all. But, when her secret does come out, their reactions might surprise her.

In a poorly informed bout of revenge, Trixie has returned to Ponyville to make Big Macintosh and Rarity fall in love, because she's convinced this will prove she is the Best Showpony in all Equestria.
