 Ramandu's daughter then appears and tells the travellers that seven years earlier, the three lords quarrelled over whether to remain at the island, to sail onwards, or to return to Narnia, and that one of the lords, in his anger, picked up the knife which the White Witch had used centuries before to kill Aslan (who was quickly thereafter resurrected).This inappropriate handling of a sacred object caused the three lords to fall into an enchanted sleep in which they had remained for seven years.Caspian and his friends are told that the only way to awaken the three sleeping lords is to sail voluntarily to the end of the world or as close as possible, and to leave behind at least one member of the crew.
