After the fall of the Captain Britain Corps, Opal Luna Saturnyne sealed the doors of the Tower Omniverse. Deciding the she would reconfigure the Captain Britain Corps, Saturnyne chose to forgo the test of Amulet of Right and Sword of Might and instead to simple confirm her own knights. To accomplish this, she commission the forging of the Starlight Sword made from the very walls of the Starlight Citadel.
During the attack of the First Horsemen of Apocalypse on the Starlight Citadel, Saturnyne intervened and set a contest where the forces of Krakoa and Arakko would each have ten swordbearers fighting in Otherworld. While preparing for the tournament, Saturnyne attempted to seduce Brian Braddock to wield the Starlight Sword and reclaim the mantle of Captain Britain. However, the Braddock siblings were able to deceive Saturnyne and allow Betsy to lay claim on the Starlight Sword. Armed with the Starlight Sword and the Sword of Might respectively, Betsy Braddock as Captain Britain and Brian Braddock as Captain Avalon joined the other Swordbearers of Krakoa in the Voltus Glade on Krakoa.
During the first round of Saturnyne's tournament, Captain Britain armed with the Starlight Sword was chosen to faced off in a swordfight with Isca the Unbeaten armed with Mercy in Avalon. The sword fight was short and brutal ending with Captain Britain and her Starlight Sword literally shattering to pieces.
