This is a poem considering the piece of broken metal from our world that was a witness to the entire history of Narnia.
A lullaby, marsh-wiggle style. (Written under a different pen name, in case you were wondering)
Though Peter doubts Aslan during the raid on Miraz’s castle, the rest of the Narnians continue to trust throughout both battles. They fight for their homes, for their kings and most importantly, for Aslan.
