The Stories of Arda fanfiction archive is a rather beautiful, author/reader friendly site, and I'm happy to be a member.

Besides my work posted here, I wrote a Maedhros/Fingon slashfic which is too graphic for a family oriented site such as this one. But adults may read it at the below URL, if so inclined (link will take you to my bio page, and you will be asked to verify your age before proceeding).

I also archive on my Live Journal

I am by no means a Tolkien or Middle-earth expert, but I try to do adequate research for the stories I write. I've added a few sites to my Links page that I use for reference besides the source material.
