The Cosmere is a universe where all of Brandon Sanderson’s adult fantasy novels (including Mistborn, the Stormlight Archive, Warbreaker, Elantris,etc) take place. It has overarching laws of magic and mythology.
The Cosmere fandom includes fans of all the works within the cosmere, since it is not necessary to be Cosmere-aware to read the books individually. However, many fans are aware of the overarching plot of all the Cosmere books.
There is a Cosmere fandom on Tumblr. Prominent cosmere blogs include onlycosmere and cosmere-cosmeme. A common tag for the cosmere fandom on tumblr is “cosmere fandom still best fandom”, originally coined by FeatherWriter.
The cosmere fandom has a great deal of interaction with its author, Brandon Sanderson. This has spawned in-jokes and traditions within the fandom. He is also active on Twitter and Reddit, and has done AMAs in the past.
RAFO stands for Read And Find Out. This is a holdover from the Wheel of Time fandom, which Brandon finished writing after Robert Jordan’s death. It is used when a fan asks a question that could potentially spoil further cosmere books or make theorizing too easy.
Word of Brandon is a play on “Word of God”, and refers to the answers to fan questions that Brandon provides online and at fan conventions. They are subject to change within canon, but many fans treat them as canon unless proven otherwise. Words of Brandon are archived at arcanum.coppermind.net.
The State of Sanderson is a writing/publishing update posted on Brandon’s blog every year. It is posted on December 19, which is Brandon’s birthday.

In 2019, aplpaca posted an image of a mango with the words “this slaps of piracy” edited over it on Tumblr. Several others posted similar images, and the meme spread. It was assumed to be a Cosmere meme, despite the meme not having any clear relation to the Cosmere.
