Magical Pony Lyrical Twilight

Magical Pony Lyrical Twilight is a fan fiction based on  written by PurpleProse. It is a crossover with the anime television series Magical Girl Lyrical Nanoha (魔法少女リリカルなのは Mahō Shōjo Ririkaru Nanoha).

It follows Twilight Sparkle as she helps a young mage named Yuuno Scrya recover a set of magical artifacts called the Jewel Seeds. To this end, she takes up the powerful device known as Raising Heart. This puts her on a direct collision course with other individuals and groups who also seek out the Jewel Seeds, including another mage named Fate Testarossa.

Synopsis
What if Nanoha never became the White Devil?

Twilight Sparkle, as everypony knows, is a magical pony by nature and profession. However, even she is confused when she encounters a mysterious ferret and an equally mysterious jewel. Forced into conflict by a monster attack, Twilight releases the power of the jewel, summoning the device known as Raising Heart.

Tasked with the retreival of a set of mysterious artifacts known as the Jewel Seeds, Twilight and her friends face an entirely new set of challenges. Unbeknownst to them, however, forces outside of Equestria are moving to claim the very same artifacts they now hunt.

Style
The overall story of Lyrical Twilight is virtually identical to that of the anime it's based on, with a number of discrepancies. Most of Friendship is Magic and Lyrical Nanoha's central characters are present, with the obvious exception of Nanoha Takamachi, as Twilight Sparkle fills the role that she would otherwise leave vacant. Chapter titles follow a similar naming convention to that of Lyrical Nanoha as well.
