Prince Caspian was the second (written order) or fourth (chronological) book in The Chronicles of Narnia and tells the story of Peter, Susan, Edmund and Lucy’s second trip to Narnia where they discover that the usurper Miraz has taken control. This evil ruler has tried to kill off the magical creatures of Narnia and is unaware of the many Narnians hiding in the remote corners of the land. The Pevensie children help the young Telmarine Prince Caspian organize his army of Talking Beasts and, with the help of the great Lion Aslan, Narnia is once again freed. Due to the anomalies found between Earth time and Narnian, this story takes place in Narnian-year 2303 and Earth year 1941.
Prince Caspian begins with the four Pevensie children at the station waiting for the train that would take them to school for the year. Before the train gets to them, they begin to feel the pull of magic on them, and they find themselves in a place they assume to be Narnia. However, they are on an island and they cannot find anything that they recognize from their first trip.
They are drawn back by the power of Susan’s horn, blown by Prince Caspian to summon help in his hour of need. Narnia, as they knew it, is no more, as more than 1,000 years have passed and their castle is in ruins, while all Narnians have retreated so far within themselves that only Aslan’s magic can wake them. Caspian has fled into the woods to escape his uncle, Miraz, who has usurped the throne. The children set out once again to save Narnia.
