I’ve added a list of reference links to the header menu. You can view all three official Avalon websites, my source for Jewel Riders pictures, and a site where you can watch all episodes of Jewel Riders.
Note: The archives for the Avalon Clubhouse are only good up until February 2006, after which they’re replaced by a generic “coming soon” page. Also, the site with Jewel Riders episodes has the European versions, and you need to register to view them. Registration is free, though. (I also haven’t gotten any junk mail from them, hooray.)
