Curios Debris nodes are found throughout the first 3 major sectors of Fallen Earth. They are often found in out-of-the-way or hostile regions, and yield boooks that the Archive Coalition in each of the sector's capitals seek. One can combine the books into collections via crafting. Then you can turn in the books to the Archive Coalition for AP (only for first turn ins) and rare materials.
Curious Debris nodes are separated by sector (Plateau, Northfields, Kaibab) and then further by model used (as they yield different books depending on the model). Please select the desired sector for more information.
