//Celestia's bedchaimbers\\
It had been a long and exhausting day but now Celestia could finally rest easy knowing her sister would take care of the dog ,the Griffin that had disturbed day court and perhaps even appease Blooblood's temper without bankrupting Equestria.
Celestia had taken a long relaxing hot bath and was about to lay down for the night when her room shook as if there was an earthquake . And honestly she would have preferred that as it was her sister screaming the fake name of the dog.
Celestia would have left her deal with the situation. But she heard such malice and hatred in her sister's voice she knew she had to stop Luna before she had a resurgence of Nightmare Moon on her goofs.
So with a degegted sigh Celestia concentrated on locating where there was a big gathering of mana as that's where Luna would most likely be. And then she teleported not even acknowledging the guards that had just rushed in or thinking on the fact that Luna was in the dungeon and the dog was supposed to be in an unused ambasator room and Celestia had even said that torture would likely yeald poor results.
//Canterlot Dungeons\\
"Feel our pain and let us hear thy howls of regret!!" was the firs thing Celestia heard as she materialized behind Luna who had taken on the form of Nightmare Moon. This was shortly followed by the sound of breaking bones and the pained howls of Bob.
"Luna?" Celestia asked hesitantly as she was almost sure that Bob was somehow an agent of Nightmare Moon this whole time. After all it would explain why he was intelligent despite being a Diamond Dog.
This was apparently the wrong thing to say as Nightmare Moon turned to smoke and reformed staring intensely at Celestia. This lasted for a mere minute but it could have been an eternity as far as the royal sisters were concerned.
"Sister!" Luna finally shouted as she jumped hoofs firs in an attempt to hug her thought to be dead sister.
"AAaaaah!" Celestia screamed breaking her stone faced mask as the image of Nightmare Moon attacked her. In this moment of panic the sun goddess used her magic to repeatedly slam Nightmare Moon into the dungeons floor causing tremors with each slam. This continued until Nightmare Moon stopped twitching and was observed by a terrified Bob and from outside the cell a shell shocked Night Shade.
"Sun Tyrant you will pay for this!" Night Shade screamed as she realized what just happened before she jumped on Celestia and cut her back while Celestia just started to realize what just happened. Then Celestia radiated enough heat from her wound to melt the blade making Night Shade jump back.
"Luna?" Celestia asked as she poked the body of her sister ignoring the pained screams of Bob or the attacking thestral.
"Stay away from the Moon goddess Tyrant." Shade screamed as she saw Celestia poking Luna. She just had to make sure the tyrant didn't hurt Luna anymore just a bit longer. After all there was enough poison on her blade to kill a fully grown dragon surely it would be enough to deal with the sun tyrant.
"Luna wake up! Come on Luna this isn't funny. Just show me you are still okay. Please?" Celestia said as she slowly picked up the unmoving form of her sister. After a few shakes Celestia resorted to trying to listen for a pulse but the constant screaming of the Diamond Dog prevented her from hearing anything so she used her magic to stop air from moving around the dogs head. Then Celestia heard it and relief washed over her before her magic began to fizzle and her vision became fuzzy. Than she fell unconscious still hugging Luna's unconscious body and the last thing she heard was the blasted screaming of that dog.
"Yes!" Night Shade cheered as she saw Celestia fall to the ground then she focused on the screaming dog." Ok doggy now just relax and I will make all the pain go away." Shade said as she approached the dog and stabbed him with a needle all the while grinning from ear to ear.
Shade was very happy. She had just single hofedly saved princess Luna from the sun tyrant and downed said tyrant.To top it all off she managed to stabilize the prisoner who she knew for a fact had yet to give up any vital information thanks to her habit of east dropping . All she had to do now was go and get a contingent of guards to help her carry the princess and the two new prisoners back to the Lunar wing.
"Don't move bat." Shade heard breaking her of her happy mood as she saw no less than 30 guards in gold armor both unicorns and pegasai charging and flying towards her.
"Buuuck." She screamed as she got out a bunch of throwing needles from the inside of her armor and threw them at the guards. Some landed hits but most hit armor then some of the pegasai and unicorns started to drop to the ground as the they fell unconscious from the poison that was on the needles.
"Don't forget she can eat magic don't let her fangs touch you or your magic fields." One of the unicorns shouted to the remaining 6 pegasai and 4 unicorn guards that were still charging and flying.
Shade charged unwilling to give up but due to her sword being destroyed she only managed to knock out 2 of the unicorns the one that shouted during the charge and was distracted and didn't notice the hoof to the face and another who tried to cast a spell which Shade stopped with a bite to the tip of the horn.
She was then dog piled by four pegasai before she was forced to stay still as the 2 remaining unicorns floated swords on her throat and neck. She was finally knocked unconscious by one of the two remaining pegasai drop kicking her with his golden shoe.
