Fairy Tail Infinity Codex Part one

The story is a "reaction fic" set in the world of Fairy Tail, taking place a few weeks after the conclusion of the Grand Magic Games and the Eclipse Gate incident. Princess Hisui gathers the mages of Fiore's top guilds (Fairy Tail, Sabertooth, Blue Pegasus, Lamia Scale, Mermaid Heel) and Jellal's team, Crime Sorcière, to view the past through a magical artifact called the Chronos Orb.

Their goal is to uncover what happened during the seven years that the core members of Fairy Tail were missing on Tenrou Island. Instead of just seeing the rise of other guilds, they discover the secret history of a mysterious, incredibly powerful, and lonely boy named Yan, who acted as a silent, unseen guardian during those dark years.

The story unfolds as the guilds watch Yan's life, from his tragic origins on a hidden continent to his impossible battles and his eventual, fateful collision with their own world's darkest secrets.
