Athena's cabin is a gray building with an owl carved over the doorway, with plain white curtains. The inside has a workshop and library, while the bunk beds that are pushed up against the wall. The library is filled with bookshelves and thousands of books, old scrolls, and has tables and chairs for them to study and read. The workshop is also filled with tables and work benches, and has cupboards filled with materials to build things. There were also some 3-D models of buildings. There were blueprints, old war maps and armor displayed on the walls.
On the side of the Athena cabin is their Armory, which is a big metal shed.
