Riot Games is expanding their work with League of Legends with its publishing arm, officially called Riot Forge. The first story-based title to come out of the initiative is called Ruined King: A League of Legends Story. This game comes to us courtesy of Airship Syndicate, the team behind the recent Darksiders Genesis. You can expect more single-player, story-based League of Legends experiences down the line with Riot Forge publishing more in the future.
