Tranquillity, an independent bitek habitat (one of only five such habitats) orbiting the gas giant Mirchusko. Tranquillity was founded to study the Ruin Ring, the remains of some forty thousand alien habitats which apparently self-destructed two thousand years ago. It was created by the strictly Christian Kulu Kingdom, but when its founder Prince Michael Saldana chose to also accept affinity gene implants and have them inherited by his children, Tranquillity was excommunicated by the Kingdom and its leaders disinherited. Since then it has flourished as a tax haven, a trustworthy base for blackhawk mating flights, and an exclusive business locale in its area of the Confederation. Calvert has inherited a trader starship, the Lady MacBeth, from his late father, but the ship was heavily damaged in an unknown incident (Calvert makes up several stories during the course of the novel to explain this incident, all false; the incident is later explained in the short story 'Escape Route' in the short story collection A Second Chance at Eden) and is no longer operational. Calvert dreams of making a big find in the Ruin Ring to finance repairs. Much to his surprise, Calvert indeed strikes lucky, finding a virtually intact memory core with the first-ever images of the reason for the Laymil racial suicide. However, decoding the information will take some time. Calvert sells his find for nearly seven million six hundred thousand fuseodollars, fixes up the Lady MacBeth and begins his life as a trader captain. He also starts a relationship with Ione Saldana, the current ruler of Tranquillity. Also on Tranquillity is Dr. Alkad Mzu, who has been imprisoned on the habitat for nearly thirty years. How she escaped the situation at the start of the novel is not explained. Mzu is kept under the watchful eye of half a dozen major Confederation intelligence agencies to ensure that her knowledge of the Alchemist is not revealed to anyone else. From time to time, Mzu asks ship captains for passage off the habitat, knowing that such requests will be vetoed by Ione Saldana. She asks both Calvert and Meyer, the captain of the Udat, for aid but both times they refuse to help after Saldana intervenes. On Lalonde Dexter encounters a group of people hiding in the jungle, led by the authoritative Laton. Laton is a 'Serpent', an Edenist who has rejected his society and, for lack of a better term,
