At the dawn of the Krakoan era, Betsy Braddock becomes the new Captain Britain while the mystical realm of Otherworld is shaken by violent conflicts. Alongside Rogue, Gambit, Jubilee, Rictor, and Apocalypse, she forms a new Excalibur team tasked with defending mutant interests beyond the boundaries of the ordinary world. Between magic, politics, and old rivalries, the group must confront Morgan Le Fay, tensions surrounding the kingdom of Avalon, and Apocalypse’s mysterious ambitions. As Krakoa seeks to establish its place within these supernatural territories, Betsy must also define what it means to carry the mantle of Captain Britain in a world where national loyalties and mutant identity often collide.
