In I Am Number Four: The Lost Files: The Fallen Legacies, you'll learn the true story behind these ill-fated members of the Garde. Before they were murdered by the Mogadorians, before Number Four was next, they were all just kids on an alien planet called Earth—discovering their powers, trying to stay hidden, and running for their lives.
Pittacus Lore is Lorien's ruling Elder. He has been on Earth preparing for the war that will decide Earth's fate. He finished recounting the story of the invasion of Earth in the I Am Number Four series and is now ready to tell another story. His whereabouts are unknown.
