I have drafts and idea for the first movie and even the second, but the thing that confuses me if what to do with Harry when Pevensies go back to Earth.
I mean the options where
1)Harry to go with Pevensies or to go to different world.
2)Harry stays in Narnia and fights the Telmaries, but because there numbers he takes the other Narnians to safety(Not before killing a lot of the Telmarines)
3)Harry fights the Telmarines and comes to stand still, like Caspian the first creates a treaty with Hadrian.Like the the part Narnians lived were called Savage lands by Telmarines because of wards and illusions and with time Telmarines forgot about them, only to remember them at Caspian's time.
If it's either two or three then Susan would know, since I am letting her have a method to contact Hadrian through Dreams and Astral form.
