I'm about 10 years late to the game, but this checklist
for writers of Laby fanfic makes me crack up. It reminds me of the episodically long fanfic via E-mail I did with one of my friends during my first year of college and into the summer. I don't even remember what the plot was, but Jareth kept dragging us back and forth out of the Labyrinth. If I recall accurately, the Labyrinth was losing magic, and, for some reason, my friend and I had to be the ones to fix it.
The one clever innovation we had was that we would write each other messages and occasionally IMs as if we were in plot ["I just had the weirdest experience; Jareth yanked me into the Labyrinth again..."], and I believe there was some writing in character from Jareth's point of view too. He, by the way, was immature, selfish, explosive, infuriating, manipulative, annoying and thoroughly unredeemable, which proved problematic as we struggled to find a justification for helping out the King of the
Anyway, we stopped writing after HUNDREDS of single-spaced pages. As we trailed off, I was stuck in the Labyrinth with only a pink computer for a communications device! OH NO!!! The non-ending ending amuses me because it makes me think of something like Dispatches From The Labyrinth.
Now I'm getting nostalgic. I should look back at that file. [Yes, I still have it all in one file and NO YOU CAN'T READ IT.]
