fanfic

or, litchrachure

Archive of Our Own - the grandmomma of them all, god bless AO3 my beloved
The Athenaeum - mostly Xena fic but does feature other fandoms. almost entirely femslash oriented
Academy of Bards - Xena fanfic, still regularly updated!
Merwolf's Home Page - Melissa Good's Xena fanfic and original/Uber fic
AUSXIP - The Bard's Corner - the fanfic section of AUSXIP (the Australian Xena Information Site). probably entirely Xena fic but I don't actually know
Tom's Xena Fan Fiction Archive - all Xena fic as far as I know
Tom's Xena Page - list of fanfic site links - links to other Xena fanfic sites, including review sites. haven't checked the veracity of any of these links so some of them are probably dead. proceed at your own risk etc
