Nebula was dreaming rather simply. He was sitting on a lone field in the night sky, waving his hoof and altering the constellations. He flew up and actually began to physically move them into place to form a shape of Luna's cutie mark.
Nebula screamed and he flew straight into the ground, shivering a little. He looked up, "L-Luna you scared me!"
Luna could not help but giggle, "My, my, you seem very fond of me," She said gesturing to the constellations.
He blushed heavily, "I-I saw the stars and I thought of you." He moved his hoof so the ones beside her began to make a large heart.
Luna smiled, and walked up to him. She kissed him passionately on the lips, her eyes closed and her heart racing.
He gasped a little bit and held her close, "Did you sneak into my dreams just to see what I was doing?" He blushed hard, "What if I was having one of... those dreams?"
He blushed a little more and gently wrapping his hooves around her neck, "Y-you're wonderful princess. I-I am proud to be your lover."
(I dunno, Nebula is really shy around it. He'd be one to maybe see her... you konw what and then be satifsied)
(Yeah, I get ya') (Time to get into action) Luna stirred a bit, it was night out, and the moon was raised half way. A weird cloud was coming from the ground in the very far distance... no, this was smoke! She got straight and ran to the window, opening the blinds, something large was set ablaze, and it was no tree either. The smell of brimstone met her nose as she opened the window... but yet, she could sense a dark, ominous force at. She then turned and ran to Nebula, "Nebula, awake at once! There is trouble about!"
Nebula shot himself up. He yelped in fear and flew straight over to his armor, grabbing it and putting it onto his body. He gulped, "Let's do this."
As they rushed out, great smoke covered the sky in toxic ranges. The breaths they would take was a mix of the air and smoke, causing them to cough as they flew along. The great Canterlot castle was set ablaze, with Celestia and BladeRunner inside.
The bat pony unfurled his wings, yet it then dawned upon him that Celestia had been the one who banished them. He looked aroundin fear, "Luna, if we go to that city then we'll be arreseted!"
In an instant, Luna was shot down by a purple beam, piercing her chest. She fell to the ground, but another pony darted out and hit her head and ribs with a large mace. Another figure appeared out of the fire and shot Nebula through the chest with a black beam, he wasn't dead... yet.
