It was almost 10 Years ago that the Tower first emerged. A mysterious demi-planar monolith containing infinite dangers but also infinite possibilities. Humanity saw it as a boon, at first. A gift from a benevolent God, or from some species with a higher risk tolerance but good intentions.

Then the 5 Year Disaster struck, and Humanity learned the truth. The Tower was a test, not a gift. A test they were failing. They doubled down on their efforts, Climbing with the fury of a dying species, but it was not enough. In the final moments before their species was annihilated, a single unimportant member of the final force of Humanity found a unique item. It sent him back to three months after the Tower emerged, to lead Humanity in a rare second chance.

But one man cannot save a world alone, even with a decade's worth of memories. Will Sutton, Pioneer, will have to deal with both allies and enemies to avoid the mistakes which plagued Humanity's first Climb if he wants to ensure that they clear the 50th Floor within 10 Years.
