The Legion Tapes are selections from an archive chronicling the world after the end. The alien Legion takes over worlds and absorbs the sentients of those worlds. They've assimilated eleven species so far, and humanity is next on their list. But even after the nations of the world fall, and even after being reduced to communicating solely by radio, humanity's fighting back.
Season 1 (subtitled The Archivist) begins four years and fifteen days after the Legion's arrival on Earth. Normally content to listen, record, and edit tapes for the Archive, Owl finds herself drawn into more and more danger after a mysterious car brings the Legion to her door.
