Celestia, daughter of Queen Helia and King Orion, always thought that she would be the main queen someday. Her dream was forever changed when Luna, the baby of the family, was born into the royal family and became the more loved princess! Envious and furious, Celestia would go far and wide to destroy Luna's life for good. When she met Discord, the mischievous spirit of Chaos and the resident of the Everfree Forest, they fell in love for only a while until Luna grew and befriended Discord.

Worried that Luna may also take the love of Celestia's life from her, Celestia concocted a plan to befall her. When she thought she had befallen her, tons of dramatic events followed! Meanwhile, Luna and Discord saw that Celestia had betrayed them for power. When Twilight and Sunset Shimmer were born, Discord plotted to have revenge on Celestia because of a heartbreaking split and cruel betrayal.

They say that power changes others... the old adage holds true to Queen Celestia, for as she became more powerful, she became more vain and unkind towards others. But, when she goes off the deep end and transforms into a malicious alter ego, only one thing can defeat her. But, how will Luna stop her own sister from enacting her wrath and plunging the world into eternal daylight? And, who was really the villain of the story?
