Celestia knew, Celestia always knew the truth, so it had to be true.
Twilight trusted her, didn't she?
And fillies always grasp to truths, to their heroes, and drink in everything life throws at them.
So two and two make five.

Sacrifice.

Celestia and Luna are all too familiar with the concept. It's a concept that has molded them, strengthened them... and in a few tragic cases, betrayed them.

When they are willing to give up everything to save those they hold most dear, what might be left could be just the thing that winds up destroying the sisters in the end.

Awesomely awesome collab partner of awesomeness is Denim_Blue, who I should mention is pretty damn awesome.

Twilight Sparkle feels like she's been waiting forever.

Alas, some things never change.

The Nightmare takes Luna again. She promises that Luna will win this time, that she will be the last one standing. Now that Luna has won, was it worth it?

Short 2nd person story about Luna going crazy evil.

What does it mean to be immortal? Celestia has lived for too long. Her memories are old. She has seen many ponies, and many places, and many times, and many stars, and many dreams.

She no longer knows what was real and what was only dreamed.

She desperately searches for the one pony she knows could not have been a dream.

A young colt asks the Night to take away his dreams.
