Swordships of Scorpio is a science fiction novel by British author Kenneth Bulmer, written under the pseudonym of Alan Burt Akers (Kenneth Bulmer). It is the fourth volume in his extensive Dray Prescot series of sword and planet novels, set on the fictional world of Kregen, a planet of the Antares star system in the constellation of Scorpio. It was first published by DAW Books in 1973. The Dray Prescot series is made of several cycles of novels, each cycle essentially forming a series within the series. In addition to being the fourth volume in the series as a whole, Swordships of Scorpio is also the fourth volume in the Delian Cycle and, like the second and third volume, is set on the fictional continent of Turismond but also introduces the island of Pandahem for the first time. The 52 completed novels of the Dray Prescot series were written by Bulmer between 1972 and 1997, when a stroke stopped his writing, also the later Dray Prescot books, after 1988, were originally only published in German. The series is in the spirit of Edgar Rice Burroughs John Carter of Mars series. (en)
