In a realm defined by a bizarre magical system called "patchworks", young Basil Avery feels trapped by his family’s heritage. As the partial heir to the Avery estate, he grapples with the weight of tradition and the responsibilities it brings. His mother, Talya Avery, the authoritative matriarch, rules decisively, while his mentor, Walther, a wise and humorous historian, attempts to guide him through the complex history of their family and its obligations. The Avery family holds several patchworks, mystical systems that grant control over various elements and processes of the realm. The most coveted are the A-class patches, like Nature Control, while the D-class patches, such as the Office of the Singularity (OOS), are less desirable and more mysterious. The Avery estate’s recent acquisition of the mysterious D VI OOS patch, with its incomplete documentation, sets off a chain of events that forces Basil and his inner circle on an unforeseen mission.
