In a world where magic is part of everyday life, the dreaded Dungeons are an essential provider of valuable resources that make modern society possible.

The people who brave the mysterious caverns and its abominable monsters are called Dungeon Runners, and Ian is one of them. Dungeons are dangerous places, but the Tower is the worst of the lot. Despite its lethality, the legendary Dungeon could make any Runner rich beyond their wildest dreams.

But the mysterious Dungeon operates on a different set of rules. Unlike any other Dungeons on the planet, a Runner needs a Ticket to enter the ancient portals leading into the Tower.

The Academy, an ancient and elusive college dedicated to nurturing elite Dungeon Runners, holds a monopoly on those Tickets. This unique position gives them plenty of power and influence. However, the Academy made a mistake when their greed led to the death of Ian's sister. Now, he will stop at nothing to crush them and their precious Tower.

Will Ian succeed in uncovering the mysteries surrounding the death of his sister? Or will he find himself caught in the schemes of the Academy's leaders?
