The electronic realm of Arcadia has been sealed away from the passage of time for decades due to a defensive shield coded by the Quarter Masters. This shield has kept them isolated and safe from the chaos of Newerth, but 8-Bit Kane accidentally sliced through the power cord during his headstrong rush through the shield to join the fray. Now all the characters of Arcadia are free to roam Newerth while the Quarter Masters duct-tape the cord, jostle consoles and blow into cartridges in a frantic attempt to reactivate the shield.
As soon as the shield went down, Big Boss Bubbles erupted from his castle and continued his relentless pursuit of two goals: Marrying Aquarius, the heavenly body he believes is destined to be his bride, and ridding the world of plumbers. In a cruel twist of irony, Big Boss doesn't quite understand how HoN works and has no idea he'll never be in a game with another Bubbles avatar. But that won't stop him from hunting plumbers during his search, and he'll do his best to clog up pipes and flood the map to call these damned wrench-turners out of hiding.
