Ardrana

Ardrana is a Dungeons & Dragons gaming world that has been around since 1985, but, since September 2007 (according to the wiki history) has been published in the form of an invitation-only MediaWiki website. Ardrana was unpublished before the Internet (only certain D&D gaming groups heard about it from its creator and curators), but when the wiki was set up, the stories of the fictional planet of Ardrana were released. Ardrana is used by the Blind Gamers Group, a blind and visually impaired group of Dungeons & Dragons players who chat using an audio-only program. Ardrana has many characters that were made up by its creators, as well as characters inspired by Aladdin, other Dungeons & Dragons worlds such as Planescape (from D&D's creators), and many more. The wiki, though not active, is not really dormant either; whenever the gaming group is actively playing, they have a little spurt of articles created by the players, for, as mentioned above, it's an invitation-only wiki.
