I've not read the Dark Tower but I whole-heartedly approve of that quote.

It's exactly what fanfic is! It's all these possible worlds built on that one line in canon, or a look, or something that goes unsaid, and the urge to explore the what if that those things offer us a glimpse of. Sometimes the stories we see are legitimate possibilities for the life of the characters behind-the-scenes, and sometimes they become outrageous extrapolations about what would happen in another setting and the characters end up being self-indulgent LJers with ridiculous friends.

I'm really glad that you liked it. Thank you for your lovely comment. ♥
