Spike led Thorax into the throne room of the Crystal Castle confident he could convince the others that the changeling could be trusted. That he meant no harm, and instead wanted to be an ally and live peacefully with them. That he could make them see Thorax for what he really was. That they could befriend the changeling and accept him as one of their own.

They didn't.

And consequences followed.

Over a thousand years ago Starswirl the Bearded wrote his last spell, an incantation that by his own admission was "broken and unfinished". Centuries later Twilight Sparkle derived from it the spell that allowed her to ascend and become an alicorn. But while she was able to reverse the effects of the spell on her friends, they weren't the only ones affected.

Co-written with River Road and Edited by The Weakest Link

This story is a sequel to Moonlights Daughter

After Songbird was reunited with her mother, she is starting to miss a little chaos in life. A thousand years ago, before the banishment of Nightmare Moon, she was friends with Discord the Lord of Chaos. Seeing him as a brother, she hated that he was turned to stone. Now she has news that he has broken free from his stone prison.

Starlight Glimmer's attempts to stop the Rainboom pulled Twilight Sparkle into many possible timestreams.

In one, Rarity and Rainbow Dash survived Nightmare Moon's victory over the forces of light, eventually attaining positions of prominence and comfort in the Nightmare's service. But when the unexpected visit of an Alicorn and Dragon sheds light on a growing conspiracy against the wicked mistress of the night, Rarity and Rainbow Dash may yet be inspired to risk what they have gained to join the fight for a better world.

Yet darkness lingers even in the hearts of some who would oppose the Nightmare, and not all agree on what a better world would look like...

This story would not have been possible without the indescribably vast help and unwavering support of Moosetasm, the pre-reading assistance of I-A-M and Waxworks, as well as the editing prowess of OnionPie and Pascoite!

Edit: The story is currently cancelled due to inactivity after a few years. However, I'm currently contemplating rebooting the story at some point, so any comments and suggestions on what you like/dislike would be appreciated.
