"Avenger of Antares Avenger of Antares is a science fiction novel written by Kenneth Bulmer under the pseudonym of Alan Burt Akers. It is the tenth 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 1975. 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 tenth volume in the series as a whole, ""Avenger"

According to Eratosthenes Beta Librae was observed to be brighter than Antares. Ptolemy, 350 years later, said it was as bright as Antares. The discrepancy may be due to Antares becoming brighter, but this is not known for certain. It could simply be caused by Beta Librae being a variable star,"
