cosmos flew back to the castle. Angry at Celestia for ereasing him from history. He didn't care much for not being in the books the worst was that his own sister did it. But from the other side it made him sad.
'what reason should she have for such deed." he thought. A few reasons comming to mind.
"no she woulnd do it because of that it's redicilous"
Slowing his speed as he approached canterlot. Cosmos prepeared to land but stoped. Giving a smirk to him self he sped down in a vertical line the streets comming closer. He channeld his magic as his horn began to glow as did the crystals on his regilia. The ponies on the ground looked above them standing still in complete shock at the closing object. They began to scream as it came closer and closer.
As cosmos was about to hit the ground he disappeared in a purple flash all the ponies gathered around the spot where the mysterious object hit the ground to find nothing but a strange mist. The stangest was as the mist began to form. Four hooves with royal horse shoos began to appear.then legs formed after that the body with the armour. tail slowly forming as the neck and head formed a crown. His eyes shot open reaveling the purple color. Some of the ponies looked in awe at the black alicorn while some said "who is he" or "what happened to him'
Cosmos smiled at himself. "you want to know, i'm prince cosmos brother of princess celestia" he said not as an anoucment but normal. He started walking on his way to the castle. Cosmos walked trough the streets looking at the houses and shops amazed at how the pony rase has evolved. Sure he had seen other species that where more evolved but it's wonderful for the pony rase. The pony's that where still on the street, going to a bar, or the occasional couple coming from a restaurant.
'Remembers me of my time with stardust wondered how her live went' cosmos thought rather sad. Thinking of the with green neon hoofed blue mare with dark blue with neon green man and tail. 'What a beautiful time i had i wish i could se her again' he thought

After a 10 minute walk. And getting some looks from the late night pony's he arrived at the castle gates two lunar guards standing there. One white pegasus and one black pegasus. As cosmos approached the gate he was blocked by the guards.
"State your business" the guard on the left said
"Coming home" cosmos said rather bluntly
"How can you live here the only ones who live here are the princesses and prince blueblood" the guard on right looked at cosmos then at the other guard
"Pst dark doesn't he look like the one who the princesses described" the guard said. Dark looked at the alicorn and his expression changed to one of shame
"your right bright it's him" dark turned to cosmos and bowed as Bright did the same. "My apologies your majesty"
"Apologies accepted" he said politely . Both of them stood back up. " one question, what are your names"
Bright was the first to answer. "My name is bright strike your majesty, and this is my brother..."
"...Dark strike" dark interrupted " we're both lieutenants of the pegasus division of the guard
"Well it was nice meeting the both of you, have a good night"
