The first volume in the Canopus in Argos: Archives series is resented as a compilation of documents, reports, letters, speeches and journal entries, and purports to be a general study of the planet Shikasta-clearly the planet Earth-to be used by history students of the higher planet Canopus and to be stored in the Canopian archives.

For eons, galactic empires have struggled against one another, and Shikasta is one of the main battlegrounds. Johar, an emissary from Canopus and the primary contributor to the archives, visits Shikasta over the millennia from the time of the giants and the biblical great flood up to the present.

With every visit he tries to distract Shikastans from the evil influences of the planet Shammat but notes with dismay the ever-growing chaos and destruction of Shikasta as its people hurl themselves towards World War III and annihilation.
