Forged in the Fire, Lost to the Flame

I recently reread and rewatched The Lion, The Witch, and The Wardrobe and I had some questions and concerns. What of the life the Pevensies left behind? Why, if they spent the majority of their life in Narnia, was it discarded and brushed off so easily? The people and the things that were left dangling in their absence really gnawed at me, so I did the only thing I knew to do...I wrote about it.
