Set in the Kingdom of Astonia, fighters known as Breakers obtain castles by breaking their core – the Obsidian Stone.
Players storm the castle, defeating monsters and defenders on the way in order to find the Obsidian Room and destroy the stone.
Players will compete for the last hit that breaks obsidian and is rewarded with ownership of the castle. All others are warped to the entrance. Within the timeframe, opposing players have the opportunity to recapture the castle by breaking Obsidian.
The owners of the castle must defend their castle and prevent opponents from stealing it.
The final owner when time runs out wins.
