Okay, last time it was Chronicles of Riddick, today we have 13th Warrior fanfiction. To me it makes no sense to write recs and lists of fanfiction in large fandoms, because there are already tons of recs out there, and I wouldn't post anything new. But, with the small fandoms I love, and enjoy reading, I want to collect what I can find for others to have a place to start from (and of course for me to have a place to check where I found what).
So, below you'll find the slash fanfiction I found so far in the 13th Warrior fandom. Enjoy!

Comments
The last fic, Return to Venden, is one I don't think I've seen. I'm getting really OCD and completist about this fandom's fic, especially the stuff written before I came along, so thank you for finding it!
I read the LJ comm of 13th Warrior as well, and I am around on LJ, but I decided to post my fandom exploits only here and my writing here and in my LJ writing journal.
Hergerbabe wrote another story as well, but I really didn't like it, and the formatting is all kinds of aweful. So, I decided to leave it out. *shrugs* I liked Return to Venden better anyway.
I'm also trying some email addresses, so keep your fingers crossed I can track her down. :)
I have some of the stories saved on my computer, but not all of them.
It made my life a lot easier, as I found it after only half an hour of snooping around, after I finished the movie and was suddenly jumped by how slashable it is.
Really, really thank you for your work in gathering this all.
I know how taxing it can be if you long to read a pairing or a fandom you just discovered, but you can't find fic anywhere (with the small fandoms at least).
Enjoy the reading!
