Twilight lives a comfortable, expected life with the security of being surrounded by her mentors and friends. As she grows into a model unicorn, a dangerous being takes hold of the volatile Brood and drives them to war, breaking a long period of peace. After years of preparation for a higher order, Twilight is chosen to ascend beyond that of a typical sorcerer in a mysterious plan to counter the impending conflict.

During her dark, trying mission Twilight will discover a caged soul and unknowingly set them free, gradually acquiring an affinity for the darkness as a result. As she struggles within deepening conflict, she must push on and fight for what she believes in. With manipulation, deceit, and betrayal storming around, will she be able to contain herself and protect those she loves, or will she succumb to the creeping darkness and abandon everything she stands for?

When Twilight receives a letter from Princess Celestia asking her to come to the castle for something very important, Twilight is puzzled. What Princess Celestia and Luna have to tell her will change the Unicorn's life forever.

Once, there was a little unicorn filly who was scared of many things. Almost every night, she found herself unable to sleep and could only be comforted by the singing of a certain lullaby. Years later, long after Rarity left home to pursue a career, Sweetie Belle tries to find a way to reconnect with her older sister, but that's proving to be more difficult than Sweetie expected. A tie-in with Ambition.

When it's too late, what happens?

As time passes everything decays, and we realize that any birthday could be our last.

The Changelings have been defeated and Shining Armor and Princess Cadence have said their vows, but that still leaves the Mane Six and others with the issue of the strain on their friendships. And among all the guests present at the reception, a few of them are going to be suprised with what new relationships are formed.

Plus, the story may get dark/adventurous or sad, I'll add the categories when there is actually a part of that category in the actual story.

This story is a sequel to Dusk and Dawn
