The World After the Fall

One day, a tower appeared in the skies of all the major cities…

Humans were suddenly summoned to become «Walkers», and they needed to clear the tower to save the world.

…

Floor 77:

The «Stone of Regression» was discovered. Walkers could now «return» to the past. Slowly… everyone left.

…

Humanity’s last hope, «Carpe Diem», was formed, joined by people who refused to abandon the world.

…

The last Walker reached floor 100. He no longer knew what to believe.
