Princess Nightmare Moon has it all. Socially awkward shut-in Twilight Sparkle has nothing of worth. Princess Nightmare Moon can acquire anything she desires. Twilight Sparkle can't seem to catch a break. Two polar opposites from completely different worlds. Yet amidst her dominant rule, Princess Nightmare Moon feels she's missing something. A certain day from her memory has been wiped... and none of her common materialistic desires can sate her quench for answers. That is until she encounters a certain young unicorn mare, who she can't seem to get off her mind.
Twilight Sparkle's dull and downtrodden life is about to get much more interesting.
