This story is a sequel to The Broken Mare

While ensuring that the Nightmare has once again been banished to the Moon, Luna is attacked while teleporting back.

A stallion has escaped from the lunar prison. Who is this pony? Is he controlled by the Nightmare? What is he after?

Is Twilight's daughter in danger?

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?

After the events of the Royal wedding and the changeling defeat, there are many changelings blasted to all portions of the country. They all regroup and retreat to where they came from, except for one apparently. One hides from the others, knowing that he is different. He wasn't involved in the invasion at all. He isn't even really a changeling, just a unicorn who somehow has the same abilities and then some. How will he hide when everypony is still wary of a possible second attack? Oh, and his name is Shifting Sands.

Mort, also known as the Pale Pony (of Death), has been tasked to take time off from his rigorous duties of reaping souls. Seeking guidance, he is directed towards the town of Ponyville, to learn about the magic of friendship from Twilight Sparkle and her friends. All he needs to do is keep his true nature a secret. That shouldn't be too difficult...right?

Pinkamina battles Death incarnate, trying to prevent the deaths of others using the cryptic powers of the Pinkie Sense. Meanwhile the Royal Sisters frown upon her messing with the fabrics of fate, and her stallion Lickity Split has been eyeing the wedding bells lately. Who is under Death's hood?

Every night when Pinkie Pie goes to bed, Pinkamina rises. Using the cryptic powers of the Pinkie Sense, she deciphers the clues and goes out to prevent the deaths of others. Meanwhile, the Stallion Lickity Split is developing feelings for Pinkie's darker half, and the Royal Sisters do NOT like Pinkamina messing with fate.

Meet Cyr. He's one of the last of his breed: A Changeling Behemoth, living battering rams that are selected and mutated from the worker caste of the Hive. Aged from centuries of labor and service to his Queen, he grows disgusted and weary of the Changeling's plots and malevolent attempts to feed on love, especially after his capture during the Canterlot wedding. Thus begins a new (and possibly more enjoyable) chapter of his existence.

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.

The Cutie Mark Crusaders, frustrated with their lack of success, begin searching through Twilight's library in an attempt to find out more information about cutie marks themselves in the hope that they will finally understand the way to get their cutie marks. However, the trio runs across an ancient book containing evil spells and they attempt to get their cutie marks in the worst way possible...
