The His Dark Materials Wiki is a free, fan-made, multilingual encyclopedia project based on the series created by Philip Pullman of the same name. The wiki contains details from the main trilogy, the three companion books (Lyra's Oxford, Once Upon a Time in the North and The Collectors) as well as The Book of Dust (La Belle Sauvage, The Secret Commonwealth, The Book of Dust Volume Three) and also contains details from the film, video game and TV series as well as pictures and behind the scenes information of other adaptions of the books (plays, radio plays and graphic novels).
The website contains plot details and spoilers from the series and fans should read the contents of it at their own risk.
The His Dark Materials Wiki was founded by Quentin on 31st March, 2006. This user did not contribute to the wiki, and it was later adopted by Lenalia Row (formerly Rowan Salazar) in 2012. This user rejoined the wiki as Musical33 in 2018. The wiki is currently run by these administrators.
Originally, the wiki was focused on providing information for fans of the series and has expanded to include Discussions for fan discussions and news sharing, blogs for sharing personal ideas about the franchise and forums for discussion on suggestions/improvements to the wiki.
The wiki was originally founded as hdm.wikia.com before, in October 2018, being moved to hdm.fandom.com. In mid-November 2019, the wiki moved to its current URL: hisdarkmaterials.fandom.com.
