Entropy
Irony's current site, which very nice fiction.
Xelloss and Filia's Space
This is Jane Clift's - AKA Elf from Space - website. It's got the best listings for Xelloss/Filia friendly sites out there. Trickster's Wedding, her 'fic, is there too -- and much worth reading.
This lady is one of the best Slayers fanartists I've seen yet. Her fanfics Slayers : Always and Trick are worth seeing. (Jen, please work more on Trick!)
