Sentinel of the Everfree

Horn smoking from the raw amount of power that was just pushed through it Luna sighs in relief as the spell takes effect. The room shakes slightly as Gaia slumps to the floor unconscious. In turn Luna leans roughly against the doorframe next to her and glares at her sister between heavy breaths. Her ragged fur slick with frothing sweat and her chest heaving after having run through the castle charging her spell. The ragged appearance mixed with the menacing glare on her sister's face was easily enough to make Celestia flinch.

"What did you do?" Celestia splays her ears flat against her head and grimaces. Luna's voice clearly laced with equal parts agitation and exhaustion. Yet her hard stare quickly softens when she notices her nephew nestled between her sister's forehooves. Any pretense of anger leaves the night princess' body as the young drake presses closer to his mother. Wilting Luna drops to the floor and gently nudges the drakes shoulder with her snout but only makes him push farther into Celestia's fluff.
"Celestia what happened?"

"I caught a spike of magical energy and was worried that the stasis crystal was failing so I came to check. As soon as I teleported however, two of the ponies helping me research the Crystal rushed to greet me claiming to have made a breakthrough." Shaking her head at Celestia's words Luna sighs.

"Of course you would appoint somepony to help you after I turned you down. What did they do?" Luna asks calmly as she sits back up onto her haunches.

"I never had the chance to find out. All they managed to get out was a greeting and how excited they were to show me something. Then as soon as they went through the doors they both froze. The rest is a little self explanatory." Bringing her hooves up to her muzzle Luna roughly tubes her tired eyes.

"I warned you what would happen sister. I told you how unstable her mind was and how she saw you, but did you listen? No." Celestia flares her wings and frowns.

"Don't turn this on me Luna, I didn't release her on purpose!" Luna simply raises her brow at her sister's statement.

"No, you only assigned ponies to poke and prod at the crystal. What did you think would happen Tia?" Shifting around in his mother's grip Spike turns to face his aunt. Wiping what little blood remained on his muzzle off with a scaled arm.

"I get that you are upset with me Luna, but can we please not do this right now." Eyeing her nephew as he gives her an awkward smile Luna groans in defeat.

"Fine. I'll let it go for now Tia, but you need to at least promise me you will try and fix things. Seeing as their Crystal is shattered you don't really have a choice anyways. Don't expect me to help you again sister." Celestia gives a strained laugh that makes Luna's frown deepen.

"I'll take care of all of your duties for the next two weeks." Silence holds between the sisters for almost a full minute before Luna's posture sags.

"Make it a full month and we have a deal."
