The Ryzom Ring is a set of tools for editing and sharing player-made "maps" that are customizable with terrain, monsters and NPCs all run by individual players. Maps can be integrated directly into The Saga of Ryzom world of Atys, where thousands of other players can experience one person's handiwork, or kept as a private sanctuary only accessible to a select few. Maps can be made exclusive to player guilds or select friends while running their own invasions or events.
