Reincarnation? Teleportation? Apocalypse? Summoning? These are the challenges and mysteries that they have to go through. Mason and his friends experience a world where everyone had vanished. The question is, are they really by themselves? Will they be able to find a way home in one piece, or will they break apart and lose something dear to them?

It is up to each individual to determine if they will be able to discover a way for everyone to return home or whether they would sacrifice one another in order to survive.
