Synopsis
Towers showed up one day, hanging over every major city in the sky.
People were pulled into them and made into "Walkers". Clear the tower, save the world. That was the deal.
Floor 77:
A "Stone of Regression" turned up. Walkers could use it to go back — to the past. One by one… they all went.
The ones who wouldn't leave formed a group. "Carpe Diem". Humanity's last holdouts.
The final Walker made it to floor 100. By then, he didn't know what any of it meant anymore.
