I made an AU Narnia music video where Edmund ends up dieing. Read the story below or you may not understand what is going on.
Peter and the others are too late to save Edmund. Now a year later after his death, Peter, Susan, and Lucy have returned to Narnia. Prince Caspian seeks their help to over throw Lord Miraz. And while they are glad to be back in Narnia, it doesnt feel the same without Ed. The siblings are distant with each other, and Peter doubts himself and everything he does. Edmunds spirit comes back to help guide the siblings before they fall a part. He tries to reassure each of them. Coming to Lucy in dreams first, and then even appears in front of Susan. Peter is upset because he did not see Edmund and resents tit. Finally Edmund appears beside Peter during the final battle. When Aslan returns he turns back events to the day Edmund was killed. This time, the siblings were able to save their brother.
