Following the events of Dawn of X, Brian was corrupted by Morgan le Fay and turned into her champion. Betsy resumed the role of Captain Britain and the leadership of a new Excalibur team. While Brian was freed from le Fay's thrall, the torture he suffered at Morgana's hands left him so angry that when he was given the choice between the Sword and Amulet once again, he took up the blade this time. Out of fear of what could happen, since the sword is capable of great good in the right hands, but it could also prove to be a dangerous weapon if Brian improperly unleashed on the world, he briefly gave the Sword of Might over to his sister for safe-keeping.
