R1 Lost Colors is a fanfiction done by AileShogun on Fanfiction.net based off the anime Code Geass: Lelouch of the Rebellion, owned by Sunrise. It was created on July 30, 2008, and is an alternate universe to the anime introducing Feite Avalon as a main character.
When Lelouch and Nunnaly were kids living in Britannia, long before the assassination of Mariane vi Britannia, they had a childhood friend named Feite Avalon. A few years after Area Eleven was established and the two had become lost to the world, Feite was exiled for reasons unknown. Shortly afterwards she was reunited with her former friends and began living with them at Ashford Academy. Even though she could no longer meet with her family due to being exiled, all seemed to be well.
Everything would change for her as she becomes involved with Zero, whom she had found out early on was Lelouch, as well as the Black Knights. With her abilities alongside that of Kallen's and Lelouch's the Black Knights begin to defy the world order and throw it into chaos. This is the story of Feite Avalon.
