Book 1

THE QUEST BEGINS HERE, WHERE MUTANTS ARE HATED AND FEARED ONCE AGAIN! The gates to Otherworld are closed - and Captain Britain is trapped on the wrong side! Usurpers Merlyn and his right-hand man, King Arthur, are now in control of Lunatic Citadel. Furies the size of Sentinels raze villages to the ground in their hunt for the "witchbreed." Cut off from Krakoa, Betsy Braddock is Otherworld's only hero - and to save her people, Betsy must recruit a round table of her own. The Knights of X gather to restore the rightful order and rescue desperate mutants - but their quest is about to get so much bigger than that. This is the era of destiny...and the fate of Otherworld lies at the center of mutantkind's future. Don't miss this essential piece of the new Krakoa!

Book 2

THE QUEST REVEALED! Betsy Braddock has assembled her Knights of X! Their mission: to save Otherworld from Merlyn and his powerful henchmen...by finding the holy grail of mutantkind. But Otherworld is vast, and innumerable armies stand in their way. When Merlyn targets the Crooked Market, a safe haven for mutantkind, the Knights must split up. Will Captain Britain find the grail? Will Gambit lead the others into a deadly trap? Death looms over the Knights - in more ways than one.

Book 3

THE FALL OF THE KNIGHTS OF X! Gambit and his team gain a momentary victory over the Furies in Crooked Market, but as the group is hit by another wave of attacks by Merlyn's army, Rachel Summer's connection with Captain Britain is severed before she can call in reinforcements. In Sevalith, the Captain and her team face off against blood thirsty vampires as they seek out a lethal potential ally. Their quest required ten knights to begin, but no one said anything about the end. A knight dies here - and the hateful quest goes on.

Book 4

BRAVE THROUGH THE DARKNESS! With Arthur and his army on their heels, all but one of the Knights of X have made it to Mercator - the province void of light. But all isn't what it seems. Will Betsy and her team be able to overcome the darkness and find the Siege Perilous?

Book 5

THY CUP RUNNETH OVER! Merlyn has finally tipped into full-blown madness: He's sent his Furies on a campaign across the realm to burn everything in sight, and only those who swear fealty to the mad king will be spared. But there is still hope! A bargain between a powerful new ally and the Knights of X may just secure the Siege Perilous and the future of Avalon. Elsewhere, Saturnyne forges an alliance with a former enemy. But trust is a fickle thing. Will these new allegiances bring triumph or ruin for the mutants of Otherworld?
