It's Not Easy Being Green

Prologue - Twi's Letter

The night was still, all but for a cool breeze which blew over the towns of Equestria, and the slowly drifting clouds. Birds silently roosted in their trees, all the statues in the Royal Sculpture Garden stood deplorably as leaves rustled and blew around them, and  all ponies were settling to sleep through my beautiful night. All ponies except two - us, the princesses.

Slowly, thinking of nothing but the pure hatred I had for the dear, kind, fair JUST Princess Celestia, sarcasm intended, I walked into my sister's room to see if she would even notice me (as far as I knew, she never had) and she didn't - well, not for the first 10 seconds. The ignorant, neglecting mare only actually realized when suddenly a little cloud of green fire swooped in through the window, and I jumped. Then she adressed me .

"Well hello Luna! Would you like to hear my student's latest ramblings on a scroll she sends me each week?" she asked me, clearly showing she didn't like Twilight Sparkle.

"Indeed I would, sister. Thank you." At least my just wonderful sister was actually talking to me in a friendly way, unlike some other occasions I can think of! I lowered myself into a sitting position and waited.

"Dear Princess Celestia," she began in a high, mocking tone, "today I learned that you don't have to be pretty on the outside to be pretty on the inside, and" she changed her tone, indicating she realized this was the pink one's dictation, "even if somepony seems reallyreally pretty, they could be the most meanest and evilististististist pony you've ever met!" she moved back into Twilight. "Sometimes things aren't as they seem at all, so you have to be open to all your options, just in case that somepony (or some-serpent, as it may be!) turns out to not be what you think it is. Your faithful student, Twilight Sparkle." She swapped to her normal voice.

"Well, that was stupid. I hate this part of my job; remind me next time to skip this part of ruling a country." She was one of those looks-nice-but-is-really-evil ponies, I thought, and a plan began to form in my mind, something to teach her a lesson that would last a long time...
