Sunset was troubled as she sat in her room. 'It's not possible! There's no way!' Sunset's mind flashed back to stories she'd heard in her youth back in Equestria. In specific, the legend of the mare in the moon. The same story that told of Princess Luna growing jealous of her sister, and trying to bring about eternal night. And how Princess Twilight and her friends used The Elements of Harmony to purify her and free Princess Luna. What troubled Sunset, was how similar 'Nightshade' looked to Nightmare Moon's appearance. But how could she have possibly survived? And how did she get here? "There's gott be SOME answer to this..." Sunset whipped out her phone, and dialed up a number. "Gold? Something's come up. And it can't wait. Let's just say it concerns your little visit to Equestria. How soon can you come over? Okay. Good. See you then." Sunset didn't have to wait long when she heard the beating of wings outside. "Glad you could make it. Come on in Gold. You too Crimson. Help yourself to something out of the fridge."
"So what's the emergency Sunset?", Gold asked.
"It's about that new girl we met today. Nightshade."
"What about her? And what does this have to do with that trip to Equestria?"
"Gold...I don't think you and the others came back alone. Haven't you taken a good look at Nightshade? Doesn't she look familiar?"
"Familiar how?"
"A certain legend of Princess Luna's dark half?"
"Wait. Are you saying?"
Sunset nodded.
"But...how?! How could she even be alive? Shouldn't the Elements of Harmony have destroyed her?"
"I'm not so sure. From what Princess Celestia told me, The Elements of Harmony have the power to seal or purify. But she never said anything about destruction. So it's very possible some small piece of her essence survived. And I'm willing to bet she's spent all her time in Equestria gathering her strength over time. But she was probably missing something to return her to a physical body. Or at least, that WAS a problem for her. Until, you and the guys got sent to Equestria."
"Okay. But how do we factor into this?"
"Like we saw at Duelist Kingdom, Burst unlocked his dragonic powers and got super powerful monster to boot. Also, Burst gained powerful magic. And when he was sent to Equestria with the rest of you, it must have leaked out because he wasn't quite used to his new form. And I'll give you one guess who picked up on the source."
"Nightmare Moon. So she used the excess magic to make herself whole again, and tracked it through the portal. And you're saying she's here? In our school?"
Sunset nodded. "I'm not sure why she's here, but I don't think we should let our guard down."
"So what do we tell the others? We don't wanna panic everyone."
"Chances are, Nightmare's going to try and continue her plans for eternal night. But at the same time, we can't let her know we're onto her. From what I've sensed, she's got full access to her magic unlike us. And that makes us vulnerable. So at the moment, we wait for Nightmare to make her move."
"Sweet Celestia.", Gold said with a sigh. "Maybe we should have seen this coming. I mean, Burst's defeated the Sombra and Tirek of this world. Maybe we should have guesses she's show up again."
"Thanks for coming by Gold. We'd better sleep lightly tonight." Sunset kissed Gold goodbye. "Stay safe Gold."
"You too Sunset. C'mon Crimson. Let's head home."
"Coming!" Crimson swallowed the last contents of the soda he was drinking, and they were soon on their way. Sunset sighed as she contemplated their next move.
'What's Nightmare Moon doing here anyway? Just what is she planning?' Sunset then looked at the journal Princess Twilight had given her. 'If things get really bad, it wouldn't hurt to have some back-up on hand....
