"The Lurker's Guide is a volunteer effort encompassing documents maintained by many Babylon 5 fans, as well as a lot of original material not found elsewhere. It's not associated in any kind of official way with the show"
The Lurker's Guide (http://www.midwinter.com/lurk/) was started before the original airing of The Gathering. It is an unofficial guide to the Babylon 5 universe. It collects a lot of information that would otherwise require exhaustive searches or be otherwise unavailable.
It was originally hosted on hyperion.com; the Hyperion class heavy cruiser is named as a nod to that site.
The Lurker's Guide is considered a secondary reference source for this wiki.
