Keran_Shadlag of KFU has cracked Okrand's Atlantean language! This site provides all the info you could need about learning this amazing fictional language.
Probably the most in-depth Atlantis site out there, even bigger than this one. ;-)
Sign up for the webring here, but it's also a really good site. Be sure to check out the fanart page.
A fansite dedicated to Helga Sinclair, with a lot of in-depth information.
TONS of screencaps! It was a huge help back when the movie was not out on DVD yet.
Really, really cool Disney fanart here by one incredible artist.
Almost every animated heroine you could ever think of is there, including Audrey, Helga, and Kida!
Has some good info on it, but prepare for a lot of ads!
The first Atlantis site I ever found; lots of stuff. Part of a site dedicated to Walt Disney Feature Animation.
Another old A:TLE fansite, hasn't been updated since 2001 but is still worth a look.
