New Ninjago City used to be a wonderful place to live. Until the Overlord came along. He built an army of nindroids and made them build a wall to keep us within the city. Now we are his prisoners. The nindroids are always going around keeping watch and making sure everyone is following the rules. If they see anyone doing something that they don't like they kill them immediately. The worst part is the ninja are missing. They haven't been seen since the wall was built. Now no one can save us. Where are the ninja?
