Aria: Canticle of the Monomyth

Aria: Canticle of the Monomyth was a role-playing game published by Last Unicorn Games in 1994. Unlike many other role-playing games which centered on individual characters in a pre-set game world, Aria was intended to facilitate the creation of gameworlds, complete with cultures, histories, and politics. Players play not a single character, but a series of characters across the history of the game world, in essence playing the role of a given guild, city or culture, and telling a larger, grander story than would be accomplished with individual characters.""
