In a world of brass and steam, Twilight Sparkle had thought she had made a life-changing discovery with the invention of the telescope. For better or worse, she was correct.

Now her discovery has not only changed her life, but the lives of those she seeks out in her desperate attempt to contact the only other creature as lonely as Twilight herself.

It all would have been much simpler, but it had to be the one Twilight could only call The Mare on the Moon.

Decidedly not within walking distance, then.

Cadance isn't Sombra. But Sombra's leadership is all the crystal ponies remember, a ruler they had to love at all costs, with the final payment being their own lives. And as they gradually come to see their new Princess as leader instead of savior, too much of that residual fear is being transferred to her. They praise her, adore her, refuse to correct her no matter what she does -- because they live in terror of the consequences for doing anything else. They have yet to find their own voices, and may go on repeating hers until Celestia and Luna switch shifts. So how can she make them tell her when she's wrong, see that there's nothing to be afraid of, and take the next step in coming back to themselves once and for all?

Forbidding them to do anything other than criticize her should do the trick, right?

...right?

A year has passed since the fateful night - and day - of Luna's return. Regret and insecurity plague her still, but slowly and surely, she is getting better. A sister's love proves itself a treasure in trying times.

Patience, forbearance and a sense of humour to brighten dark moods help, too.
