На окраине созвездия Прядь Мирцеи, в далекой галактической ветви Персеид находится система Пурпурной Розы, состоящая из трех звезд — Лорки, Синга и Сирены. Вокруг Сирены вращается достопримечательная планета Кадуол, с незапамятных времен защищенная от колонизации и эксплуатации уставом открывшего ее, но уже практически не существующего земного Общества натуралистов. Административное управление Кадуола находится на станции Араминта, где молодой человек по имени Глоуэн Клатток пытается определить, какую карьеру он может сделать в иерархическом, связанном множеством ограничений обществе Кадуола.
Кадуол — планета необычайной красоты. Для того, чтобы защитить ее, Общество натуралистов учредило Хартию, ограничивающую количество поселенцев — служащих Заповедника, обеспечивающих соблюдение его законов. Эти законы запрещают строительство других городов, добычу ископаемых и развитие другой промышленности. Только шестеро «агентов», их прямые потомки и их персонал имеют право постоянно проживать на планете: их основная функция заключается в предотвращении переселения на планету других людей, хотя туристам позволяют временно посещать особые заповедные приюты, позволяющие любоваться ландшафтами и любопытными образцами местной фауны.
At the remote end of Mircea's Wisp, far out on the galaxy's Perseid Arm, is the Purple Rose System, containing the three stars Lorca, Sing and Syrene. Around Syrene swings the spectacular planet Cadwal, which the now defunct Naturalist Society of Earth long ago chartered to forever protect from exploitation. Cadwal is administered from Araminta Station — where young Glawen Clattuc wonders what the future may hold for him in the hierarchic, constrained society of Cadwal.
Cadwal is a planet of extraordinary beauty. To protect it, the "Naturalist Society" has set up a Charter which allows only limited settlement on the planet in order to enforce the laws of the Conservancy. These laws forbid extensive human habitations, mining and other exploitation activities. Only six "Agents" and their staff are allowed to reside permanently on the planet: their main function is to prevent other humans from establishing residence, although tourists are allowed in specially designed lodges, overlooking sites of natural beauty and interest.
John Holbrook Vance was an American writer widely celebrated for his imaginative contributions to science fiction, fantasy, and mystery literature. Over a career that spanned more than six decades, he became known for richly detailed worlds, inventive language, and stories that combined adventure with sharp social observation. His work influenced generations of speculative fiction writers and helped expand the literary possibilities of the genre. Vance wrote more than sixty books and numerous short stories, many first appearing in science fiction magazines before later being expanded into novels and collections. His fiction was widely translated and developed an international readership. Vance grew up in California and spent part of his youth on a ranch near the Sacramento River delta, where he developed a love of the outdoors and an appetite for reading. The family experienced financial hardship during the Great Depression, prompting him to take a variety of jobs before completing his studies at the University of California, Berkeley. During these years he worked in several trades and cultivated interests in music, travel, and sailing, experiences that later informed many of the settings and themes in his fiction. Before becoming a full-time writer he held numerous occupations, including shipyard worker, merchant seaman, carpenter, and surveyor. His earliest published story appeared in the mid 1940s in a science fiction magazine, marking the beginning of a long writing career. Throughout the following decades he produced stories across multiple genres, though he became best known for science fiction and fantasy cycles that combined imaginative settings with elaborate cultures and social systems. Among his most famous works are The Dragon Masters and The Last Castle, both of which received Hugo Awards. The Last Castle also earned the Nebula Award, confirming Vance's reputation as one of the most distinctive voices in speculative fiction. His fantasy trilogy Lyonesse later received the World Fantasy Award, while his memoir This Is Me, Jack Vance! earned another Hugo decades later. In addition to speculative fiction, Vance wrote several mystery novels, some under pseudonyms including Ellery Queen. These works often blended crime elements with psychological or social themes and sometimes anticipated ideas that later appeared in his science fiction. His storytelling frequently emphasized cultural conflict, moral ambiguity, and intricate social customs rather than large-scale warfare, setting him apart from many contemporaries in the genre. Vance maintained close friendships with other science fiction writers and participated in literary communities that shaped postwar American speculative fiction. He traveled widely with his family and spent extended periods abroad, experiences that influenced the exotic settings and cosmopolitan tone found in many of his books. Music also played a role in his life and writing, reflecting his long-standing enthusiasm for traditional jazz. Despite gradually losing his eyesight later in life, Vance continued writing with the aid of specialized software and completed both fiction and autobiography in his later years. Over time his reputation grew steadily, and he received numerous honors, including the World Fantasy Award for Life Achievement and recognition as a Grand Master by the Science Fiction and Fantasy Writers of America. Critics and fellow writers often praised his distinctive style, wit, and imagination, and his stories remain widely read within the science fiction and fantasy community.
