The rebel files are stored in a small room within the rebels' base in the underground subway system. The files include the locations of rebel bases, weapons, safe houses, supply depots, members, and positions. The files are hand-drawn and kept within crates.

Inside was a stack of weathered paper with meticulous hand-drawn records of each and every base, safe house, and supply depot. Zach lifted it to reveal several maps, showing the exact location of the buildings. It also showed several more entrances to the underground subway system that they were inside now. After the maps were records of the supply of weapons, and then possible strategies for attacking the Authorities.
