Halopedia

"Halopedia can tell you nearly anything you may need to know about Halo. Halopedia is also a wiki, which means it's constantly expanding. It knows everything about the Halo games, books, upcoming movie, and other appearances, and with your help, it can grow even larger. But how can one trust a wiki? Surely some crazy could come in and troll the entire place up. Well... they could, but they wouldn't get too far. Halopedia is guarded by rabid watchdog-like fans who are constantly watching the Recent Changes page to check for the slightest error, either grammar or factual. Okay, that's a bit exaggerated. The real deal is that Halopedia is under almost constant watch by someone who can set everything right. With 3 very responsible sysops and a mob of other users, Halopedia is in safe hands. Be sure to check out Halopedia and even you could find something to contribute."

- Dragonclaws's description of the wiki. (2006)

Halopedia is a wiki about the Halo fictional universe. It covers the Halo video games, from Halo: Combat Evolved to Halo 5: Guardians; tie-in media and merchandise including published literature, films and action figures; as well as notable people associated with the franchise. Much like Wookieepedia, Halopedia is a fan-driven encyclopedia and is not an official party of the Halo franchise; thus, it is not itself a primary source of Halo information but rather an aggregate of content based on official media.

Halopedia runs on MediaWiki and is privately hosted. The site is also available in several other languages, including French, German, Greek, Italian, Japanese, Polish, Spanish, Korean and Russian. However, the English one is the most up-to-date version, with the others having very little content.

History and description
Halo Wiki, as it was known back then, was founded by, with the help of who hosted the site, and launched on November 4, 2004. Initially created to supplement his clan, the site shifted its focus to cover the Halo universe in later periods. After the creation of halowiki.net, the site was renamed to "Halopedia" and moved its domain to www.halopedia.org. Halopedia and halowiki.net remained sister projects with very different goals; Halopedia concerned itself with the canon of the Halo universe, while halowiki.net was essentially a "multiplayer repository"; halowiki.net has since gone inactive. Since the renaming, Halopedia has actively documented the developments of the Halo franchise and the fictional universe, along with gameplay information and help.

In 2006, the original host was unable to financially support the wiki, prompting Halopedia to merge with Wikia's Halo Wiki site. From 2007 to 2010, Halopedia was one of Wikia's most active and popular wikis following the release of Halo 3, Halo 3: ODST and Halo: Reach. In 2009, the wiki was awarded as the "Best Resource Website of 2009" by Hawty McBloggy, later a member of 343 Industries.

Following a mandatory skin change and stricter Terms of Use in mid-2010 by Wikia, Halopedia moved back to an independent domain, hosted by the previous host.

Halopedia has come to be regarded as accurate and reliable among the Halo fanbase and media alike, and has been used as a source for several works of published literature.
