Ponyquest

You wake up one day and see Alicorna Amuleta, your former enemy, in all of her glory and more. You thought she'd escaped from her prison: the Alicorn Amulet. She looks like Nightmare Moon now, only with a few differences. Her mane is a deep ruby with black streaks and her eyes are red. Her coat has now turned midnight blue and she is wearing Nightmare Moon's armour. She has your mane, however,

"Hello, Princess Celestia Alicornia…" cackles Alicorna. "How is it to have another-no wait, two princesses more?"

"Alicorna. I sealed you away in the amulet in order to reform you. Instead, you took over Trixie Lulamoon through your dark magic, making her evil. Lucky my faithful student could save her. I used my magic- the magic of friendship- in order to make you a good pony. Unfortunately, this is not what has happened," you say, "and I will not stand for it."

Alicorna takes the amulet and puts it on, making her even more powerful than you and all of Equestria's magic combined.

"Who's the ruler now, CELESTIA?" laughs Alicorna.

"Me." you shout.

"I don't think so."

You engage in a fight with Alicorna Amuleta. She teleports Cadence to where she stands, and gives the amulet to Cadence.

"Where am I?" she asks.

"You're in the castle, with me, your princess, I mean, QUEEN!" You see Alicorna's magic hit Cadence as she is regressed in age to before her birth.

"Stop it. Stop it. STOP IT!!!" she screams as she disappears into thin air.

"Dear Princess Twilight Sparkle…."
