To my side, all true Narnians! Would you wait till your new masters have killed you all, one by one?

It is Narnia's darkest hour. A false Aslan is commanding all Narnians to work for the cruel Calormenes and striking terror into every heart. King Tirian's only hope is to call Eustace and Jill back to Narnia in an attempt to find the true Aslan and restore peace to the land. But a mighty battle lies ahead.
