During the climb, there appear returning stones and most of the walkers use it in order to go back to the past, however the present doesn't change. The MC is an OP "stabbing" maniac. In the end je cleared this Tower just to find out, that he's cleared the tutorial, Earth is a planet in some spare dimensions that is connected to the roots of the World tree, he's in a coma and the Tower is a nightmare that he can't leave cuz the owner of this tower is a demon who wants a promotion... So he decided not to confirm the clear of the Tower, kill the demon and escape the Tower through the roof... Just to end up in Chaos, which is somewhere above the roots but on the lowest point of the World tree... and is also basically a purgatory (space for dead to gather). OH, and there are 12 monarchs, basically autorative figures as Gods, who are interested in the MC, especially the Dark Monarch.
