Out of the Silent Planet is a science fiction novel by the British author C. S. Lewis, published in 1938 by John Lane, The Bodley Head.[2] Five years later it was published in the U.S. (MacMillan, 1943). Two sequels were published in 1943 and 1945, completing the so-called Cosmic Trilogy or The Space Trilogy.[a]The fragment of another sequel, evidently set prior to Perelandra and That Hideous Strength, was published as "The Dark Tower" in a 1977 collection of short fiction by Lewis (deceased 1963) and essays by four others, The Dark Tower and Other Stories (Collins, ISBN 0-00-222155-1)The hrossa, séroni, and pfifltriggi are several of the races living on Mars in Larry Niven's 1999 novel Rainbow Mars; they are referred to as the "Pious Ones" by the Barsoomian races. The hrossa are called the "Fishers", the pfifltriggi the "Smiths", and the séroni the "High Folk". The pfifltriggi are one of the races who chose to ride to Earth on Yggdrasil.

The séroni appear at the beginning of the second volume of The League of Extraordinary Gentlemen as one of the Martian races allied against the "mollusc invaders" (the Martians from The War of the Worlds).

In Scarlet Traces: The Great Game, a hieroglyphics-filled chamber seems to show the hrossa, séroni, and pfifltriggi as the original races of Mars, that were wiped out by the arrival of the War of the Worlds Martians.In the Postscript, Lewis gives context to the story and its narration by quoting letters he, Lewis, has received from Ransom (or the person he represents). They discuss the progress made in writing this book and how different aspects of "Ransom's" adventure can be better represented. Ransom expresses frustration and dissatisfaction with this written version of his story because it can't possibly communicate the experience and awe he felt through his senses. These letters even go as far as discussing their, Ransom and Lewis's, decision to make the book fictional, as it is in reality, to better open the minds of their readers to the possibility of its truth.the "Cosmic Trilogy" series including omnibus editions of the three novels titled The Cosmic Trilogy (UK, 1990) and Space Trilogy (US, 1996).
