My lungs felt like they were filled with hot glass. Every breath scraped against my ribs, a jagged reminder that the eighteenth floor's martial arts lesson was a distant memory. The air on the nineteenth floor had weight. Sulfurous and dense, it pressed down on my collarbones until they ached.
I stared up at Mount Agony. The trail spiraled upward, a crumbling scar carved into a peak that seemed to pierce the Tower's ceiling. At my feet sat the source of my suffering.
The Boulder of Sin.
Five meters of perfectly spherical obsidian. When I placed my hand against its surface, the weight went beyond physical. Something spiritual lived in that stone, like the collective regrets of a thousand dead men pressing against my palm.
