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.
