"And after that fateful birthday, the young dragon Spike never again turned to greed. Instead, the magic that aged him was a different magic- a pure magic from before the beginning of time. It was his undying love for a unicorn mare. And thus he grew not uncontrollably or into a horrible beast, but was granted the ability to choose what he wanted to be. And he chose to be with her."
As those last words escaped the Princess's mouth, the crowd erupted in cheers. The newlywed couple embraced, staring deep into each other's eye. Not far away stood the other newlyweds, a certain pair of Wonderbolt mares. Spike's mother-figure, Twilight Sparkle, blushed as a pink party pony inched towards her. A heavily pregnant Applejack nuzzled her husband. Famous singer Sweetie Belle watched in amusement as a scholarly unicorn stallion courted her best friend, Apple Bloom. And behind Sweetie stood her proud coltfriend, Leeroy. Off to the side, a minty mare played a happy tune on her lyre beside a grey mare with a cello. It had been years since their adventures had ceased, but their bonds remained as strong as ever. And, perhaps, they'd finally found their happy ending.
