Marune: Alastor 933

A young man (provisionally called Pardero) has lost his memory—remembering almost nothing of his past.[2][3][4] Acting on good advice, he earns enough money by menial labor to travel to the Connatic's free hospital on the capital planet Numenes. There, after much research, medical technicians are able to deduce from his reactions to various stimuli that he is a Rhune from the sparsely populated planet Marune[3]—a planet illuminated by four stars (Suns). The Rhunes are a somewhat peculiar people who, among other traits, have a strong aversion to killing (unless it be in combat). From this and other clues, the man becomes convinced some enemy has caused his amnesia. He journeys home to find he is the ruler (Kaiark) of a small kingdom. He has to tread carefully, unsure of whom he can trust, in his quest to unmask his foe. Determined to unveil the identity of his enemy, who has erased his memory, he will clash with the strange customs of his people, based on the illumination provided by the four suns: in particular during the Mirk, when all the suns set in the sky and night falls, the men and women of Marune are left to strange behaviors. The novel ends abruptly.[5]
