42 Years before Luna's banishment
Luna was very, very excited. It had just been announced that World Of Warcraft was going to cut back costs on the premium subscriptions that it offered. She was pacing back and forth through her chambers. She needed a way to level grind more efficiently, as her current method, quite frankly yielded close to no progress at all. She looked down at the city of Canterlot with melancholy in her expression.
She saw a carriage shaped like a banana approaching the castle, from which her sister stepped out. Luna knew that today was the day that Celestia restocked on Tortilla chips, and this made her happy. She decided to check out videos about tortilla chips on Youtube. She found one, and left a comment promptly.
1337LUN43X7R3M3: I love tortilla chips. They are great while playing World of Warcraft.
She pressed the post button, and went off to bed. The next morning, she logged back onto her computer, and went back on Youtube. She checked her inbox and saw that there was a reply. She clicked on the comment reply and opened it.
She looked at it in horror.
UberBladeSniperXtreme<3Celestia: Lol Noob, ur a gay. Only gays play WoW.
She seethed with rage, and vowed the destruction of all those who did not share the same opinions that she did. She started plotting to destroy those who despised her, and take over Equestria, bringing eternal night. Youtube commenters would know the wrath of Luna. She proceeded to post about it on LiveJournal. She talked about how her sister was ruining her life, and made sure to include plenty of crying emoticons.
