Chapter Two: Rebellion
The next day Zane and Luna were in the throne room
" Did you two really expect us to sit ideally by while they all basked in your precious light and warmth? There Can only be one ruling pair in Equestria and that pair shall be US" said Zane and Luna as they lit their horns to bring about snow in the summer and night in the day. The power of their actions transformed them and Luna's coat turned pure black and her eyes and teeth turned to those of a demon. Thestral wings took the place of her feathered ones. Zane's Coat turned Icy blue and his eyes glowed blue as well and his teeth became fanged like a vampire's and his mane and tail swirled like a snow storm.
" Zane,Luna we will not fight You" said Kai
" Luna, I am Nightmare Moon" said Nightmare
" And I am not Zane, I am Blizzard Snow" said Blizzard. Then they attacked their siblings as a night time snow storm raged outside." From this Moment forth the winter night shall last FOREVER" Shouted Nightmare and Blizzard simultaneously then laughed maniacally
" We're sorry sister and brother but you have given us no choice" said Kai "But to use these" said Celestia before opening the vault to the Elements of Harmony. Kai wielded Loyalty, generosity, and Laughter while Celestia used Friendship, Kindness,and Honesty . Blizzard Snow Saw Nightmare Moon about to get blasted by a terrifying rainbow so he flew to protect her. They both ended up getting hit by the rainbow of destruction and were blasted to the nearest celestial orb, the Moon. There they would remain for a thousand years while their brother and sister ruled.
