There are more than one main character they are susan, lucy, edmund, and peter. You could narrow that down to Susan & edmund though. There is also A Faun called Mr. Tumnus, a lion called Asland, and a 'Queen' they call the white witch. The setting is started in a mans house with a wardrobe then moves to a land called narnia. The conflict is White Witch doing something. They resolve this by having a war and winning. I relize I am very unclear on but i havnt read this book in a long time.
