Jason and his friends just wanted to spend a week at the lake house. Time to relax, hang out, and catch up on old times. Then the System arrived.

They don’t know the rules. They don’t know what’s coming next. What they do know is; they need to reinforce and expand their fort while protecting it, keep leveling up, and explore a dangerous new world.

Xavier Collins was sitting in class when the System integrated Earth into the Greater Universe, where countless vast kingdoms, empires, and collectives battle for domination.
