The concept of "Out of Cavern", or "OOC", treats the Myst series and its contents as fictional. This term was coined during the lead-up to Uru's original release in 2003, during which time Cyan operated the game as if it were actually a real sequence of events and locations. It was co-opted from traditional table-top and live-action role-playing terminology, where OOC refers to being "out of character". From an OOC perspective, the DRC, the D'ni Cavern, and all of the history surrounding it are fictional, and the Myst universe exists only as part of a game. Cyan Worlds is the creator of these games, and in the case of Uru is directly responsible for the development and release of the content that goes into the game; the DRC is their "front" for this process, serving merely as a story element to explain the continual development of the game from within the context of the game itself (or "[article title=In Cavern]In-Cavern[/article]").
