Darkness Rising
Quite possibly the best, most complete Slayersfic bibliography/archive.

Silent Steel's Fanfics, Songfics, Fanart, and Other Silly Things
Lots of wonderful Zelgadiss/Lina stories, plus toons! ^_^

The Realm of Insanity
Manami's site has tons of really good Xelloss/Lina fic.

Slayers Elsewhere
Tavichan's great Xelloss/Lina epic Slayers Elsewhere, plus some side stories.

Eugene's animation+
This site has what is possibly the kewlest fanart I have encountered in any fandom, ever. Eugene concentrates on Zelgadiss and Xelloss, and she has some amazing Zelgadiss/Lina pics.

Slayers Sorcery
This site is in Italian, but you should go there even if, like me, you can't understand the Italian. Great fanart, amoungst other things.

Listbot's xellinaxeros homepage
As you probably guessed, this is the listbot page for the zellinaxeros list. Go here to join the list or view the list archives.

The Mazoku's Lair of Darkness
Rather new, but still nice site. Has fanfic, 'toons, and the Slayers crew's horiscopes.

mysticdragon3's Zel-Lina Shrine
A Zel/Lina couple shrine! Can we say "spiff"?

Give a Reason: A Slayers Page
Nice site with character info and a nice little Lina/Zel shrine.

Tenmadetodoke's Zel, Xel, and Val Shrine
Self-explanitory. Also has a small Lina/Xelloss couple shrine.

The Lord of Nightmare's Mazoku Shrine
Great site, with an emphasis on the mazoku of the Slayers world.

Sailor Star Saturn's Super Slayers Site
Lovely alliteration aside, this small site is quite fun.

C.A.A.Z. – Church Against Amelia & Zel
C.A.A.Z. mainatins that Amelia and Zel as a couple is horribly, horribly wrong. (I agree.)

Unofficial Site Against Amelia and Zelgadis Coupledom
Another site against that most disgusting pairing.

Thalia's Slayers Garden
Thalia's site is quite impressive, particularly some of the picture shrines.

All Zel, at the time!
Great site for Zel fans.

The ULTIMATE Zelgadis Shrine
Another fab site for Zel lovers.

Ground Zeros
Rather nice page devoted to Zeros (Xelloss).

Pen's Slayers Page
Very nice site maintained by one of my fellow zelinaxeros listians. Make sure to check out the fanfic.

Zellina's Zelgadiss Gallery and Slayers Gallery
Lovely galleries.

The CG Picture Shrines
A huge site that has picture shrines for Lina (yay!), Naga, and Filia.

Slayers Universe [slayers.maison-otaku.net ver 3.993]
Beautifully designed page, with lots of info on the characters, magic, and such of Slayers. Also has great TV and Next summaries.

Lina Inverse's Slayers Page
Incredibly impressive site, tons of information.

AnimeArt Search
Sort of like Yahoo! for anime (not just anime art).

The Anime Web Turnpike
