What is "norstrilia"

Norstrilia is the only novel published by Paul Linebarger under the pseudonym Cordwainer Smith, which he used for his science-fiction works (though several related short stories were once packaged together as a short novel Quest of the Three Worlds). It takes place in Smith's Instrumentality of Mankind universe, and was heavily influenced by the classic Chinese novel Journey to the West. The novel is in part a sequel to Smith's 1962 short story " The Ballad of Lost C'Mell", featuring some of the same characters and settings.
