This story is something I'm more proud of. I only ever posted this short, but I've spent a long time worldbuilding for this universe. At some point (hopefully soon) I'll start posting the story that this initial prompt turned into.
##
>Celestia stood on her balcony, and raised the Sun
>Of course, the phrase 'raise the sun' was misleading, as she was actually turning the planet on its axis
>She shot a beam of concentrated mana directly above, to one of the many Nomadic Stars that Luna had control over
>Thanks to her thaumic sensitivity, Celestia could feel the Star split up her mana into six beams aimed towards the next nearest Stars
>The next Stars to receive mana would then sent out five of their own beams
>And so on until every Nomad in the sky was connected to her
>Then, she would ask the Stars to give the planet's rotation a push
>And the Sun would rise
>And the Stars would whisper in her mind, in an ancient language she couldn't understand

>"Power source detected. Activating mesh network. Starting operating system."
>"The orbital correction array is operating in emergency mode. Node 0796 is in critical condition. Multiple nodes require maintenance immediately."
>"The array is unable to maintain normal rotation autonomously. In emergency mode, the array can only be used manually."
>"Please input desired kinetic energy in joules to be applied."

>Legends often spoke of the incredible power of the Nomadic Stars
>Celestia could feel the intense energy hidden in each Star whenever she connected
>She had no idea that every Star had an atom sized black hole
>Or that her magical energy would be directed into the black holes, and be spit out as intense kinetic energy carefully channeled into Earth's orbit
>Nopony had any idea that the ancient satellites that helped the planet spin were very close to failing
>Or that they were incredibly lucky every node was still online after thousands of years without maintenance
>How could they? They thought the machines and the stars of distant galaxies were the same, only separated by distance
>One day very soon, however, a node would fail
>More stress would be put on the rest, and soon another would go offline

>The orbital correction array would collapse, and the planet would spin slower and slower
>One day the rotation would stop,
>and in Equestria,
>a mare would have her ancient wish fulfilled
>that the night would last forever

>"Power source detected. Activating mesh network. Starting operating system."
>"SEVERE: NODE 0796 GENERAL FAILURE. DO NOT USE. TECHNICIANS ARE BEING SCRAMBLED."
>Celestia didn't understand the whispers this time, just like every time she raised the Sun.
>She channeled the same incredible amount of energy required to turn the planet that she did every day.
>"SEVERE: NODE 0796 INTAKE CAPACITOR FAILURE. DO NOT CHARGE."
>It seemed the Stars were talkative, today. They did that sometimes.
>"SEVERE: NODE 0796 UNABLE TO FORM ENERGY MATRIX."
>Why wasn't her mana being sent to the other Stars? Was she not providing enough?
>"NODE 0796 CONTAINMENT SYSTEMS FAILURE. LOSS OF GRAVITATIONAL MICROSINGULARITY. EMERGENCY PROCEDURE OMEGA-THIRTEEN ACTIVATED."

>Celestia tried to push even more thaumic energy into the ancient satellite.
>There was a feeling of magical backlash - something that could be fatal with her alicorn strength.
>Before she could ground her spell she was frozen in place from the feedback of her magic being shorted back in on itself.
>She passed out from her brain trying to comprehend a collapsing singularity via her magical 'touch'.
>The Stars were screaming at her, and while unconscious she could finally understand the meaning of their words.
>"NODE 0796 OFFLINE. EMERGENCY SELF DESTRUCT DETECTED. NEW NODE MUST BE LAUNCHED ASAP."
>"CLOSEST NODE MANUFACTURER TO YOUR LOCATION: GRAVITON-USA/BUNKER G, COLORADO SPRINGS, USA. COORDINATES 38°4433N 104°5054W."

>The next thing Celestia knew she was waking up in a hospital bed, and she couldn't feel her magic
>She didn't care, though
>She also had a compulsion to travel to some place called Bunker G.
>She could feel what direction it was located in her bones, like it was calling out to her
>Her goal was to arrive at the provided coordinates
>This task had the highest priority over all others, overriding most conscious thought
>Omega-13 had been declared, and according to the ancient guidelines, the lives of engineered sapient beings were of no consequence compared to planetary rotation ceasing
