If you would like, I'd be more than happy to help proofreading and editing the storywriters' works. I'm fairly free these days. I'm also more apt at filling in the gaps of a skeleton rather than creating a whole new narrative. If you're interested, here is where you can browse through my work (although, despite my previous claim, all of these are all mine without a co-author laying the groundwork for me):

Crystalline Tangles - a fanfiction set in Norrath, EverQuest's world. But it's generic. Very generic fantasy; EQ doesn't have much in way of canon to work with. I intend the focus to be characterization and intrigue rather than sword-and-sorcery action.

A King's Trial - a fanfiction set in Arda, LOTR's world. Post-War of the Ring, focused on King Telcontar's reign and the leftover of the late Steward of Gondor, with some exploration of Eowyn/Faramir and Aragorn/Arwen relationships as background. (No, it's not a romance piece.) Done in practice of quasi-archaic style that, naturally, imitates soem of Tolkien's. This is a piece with which I'm content enough to use as a showcase work, but if you aren't a fan of the LOTR books -- as opposed to the movie, you might not be particularly interested.
