Narnia and Doctor Who? Two of my favourite things in the world, together in one wonderful fic!

"That tree embodies all the possibilities of Gallifrey. It lives on as long as some part of Gallifrey exists. It lives because of you. You are Gallifrey now."

An absolutely brilliant concept. You linked the two fandoms so well. I love the conversation between Aslan and the Doctor, the Doctor's helplessness and Aslan's calmness and majesty.
