Discord, the spirit of Chaos was given redemption by Princess Celestia when discovering the magic of friendship. However, his true nature gets the better of him, and once again he uses his power for his own will. The elements of Harmony are protected from him, but there was nothing saying that the element bearers couldn't be eliminated.

Realizing that Discord has no intention of stopping and has rendered the elements useless, Celestia and Luna must face Discord in a final showdown. His powers are too great for them to fight when they are in their current form, but perhaps two alicorns are not needed. Maybe only one.

Edit: This is an old story, you have been warned.
Spawn 666, Nickname: Skid.
Just a regular one of the hive until he was blasted the farthest away from the hive mother and now has to think for himself for the first time in his life. He has to think on his feet and make a disguise for himself based on his imagination of a pony he crafted in haste. He now has one job: Infiltrate Ponyville for his Liege, his queen. But being away from the hive means he is going to develop a personality, and that is something someone in the hive should be without, except in smaller doses. Will his new life affect his job, or will he forsake the innocent ponies for the one he is supposed to serve?
[R] Means the chapter is entirely revised.
[SR] Means it had been slightly revised, but is not the final copy. This means there is likely plot holes and information missing.

The following was a collection of letters written to Twilight Sparkle, which were then delivered to princess Celestia herself. They contain an account by the former captain of the guard, Shining Armor, of what occurred in one of Luna's research facilities. The details are unsettling to say the least.

This story is a sequel to The Retribution of Chrysalis

Queen Chrysalis has spent the last few weeks living with Twilight Sparkle, hiding from the public eye and awaiting news of Princess Celestia's changeling relief effort. When Shining Armor discovers a critically injured changeling on the outskirts of Appleloosa, to Chrysalis' infinite delight, her hope for her race's survival is instantly reinvigorated.

But then the Canterlot hospital refuses to properly care for the changeling, leaving Cadance to provide the love he requires. The publicity forces Chrysalis to reveal herself to a fearful populace, driving her into the hooves of a fellow outcast. And perhaps worst of all, the awakened changeling has forsaken his queen. In his eyes, and in those of all of Equestria, Chrysalis must once again redeem herself.
