This is a Recap Page for The Descendants. See the main page for details.
The main series currently has four volumes, each with it's own rough Story Arc:
Volume 1: Welcome to Freeland House deals with introducing the main characters and how they go from refugees to heroes and their relationships with the supporting cast. Along the way, the primary villains, Vincent Liedecker, Brother Wright, Morganna and Simon Talbot are introduced and revelations are made about the nature of the setting's psionic powers.
Volume 2: Magic and Machines follows up on the aftermath of Volume 1 and works to expand more on the world and culture of the setting. It also introduces new enemies such as enemies from Faerie, and the Church Militant group, The Sineaters. The Volume ends with magic returning to the world
Volume 3: The Bright, Bright Summer is Exactly What It Says on the Tin, including a Beach Episode. It also follows the main characters as they deal with new magical threats while protecting and recruiting kids for a new Super Hero School. The volume winds down with the foundation of the school, the students of which are the subject of a separate set of stories
Volume 4: Confluence is a Continuity Cavalcade, bringing back and in most cases upgrading old villains, revisiting previous plot points, and firing off some of the series's many Chekhov's Guns. Many long running plots were resolved of given new life in this volume.
Volume 5: How the World Changes continues what Volume 4 started, revealing even more of the setting's mysteries while loading a whole new set of Chekhov's Guns. The threat that descendants might not remain as well treated in the US as they've enjoyed appears, and Project Tome scores a massive win.
Half of Volume 5 sees the group split up between Mayfield and a beach house at Dawson Bay, switching from one to the other for stories. Word Of God says that it will end with the full return of Morganna.
