Dark Souls is an action role-playing series developed by FromSoftware, beginning with the original game in 2011. Its online systems let players interact across connected worlds, including summoning other players for cooperative support. The summoning audio became recognizable through repeated use during difficult areas and boss encounters. Gameplay videos, streams, and fan edits later carried it beyond the games, where creators use it as shorthand for backup arriving, cooperation beginning, or someone making an unusually dramatic entrance.
