The Fivefold Infernal Contract
You enter a circular dungeon chamber of polished basalt and black iron. A five-spoked arch rises from the floor, each spoke ending in a recessed infernal glyph. Thin red light pulses beneath the plates like a heartbeat, while the air smells of hot metal, burnt sugar, and old blood. Around the walls, brass letters crawl slowly across a contract-poem. Above the arch, a cracked obsidian lens watches the room. Five channels in the floor terminate at the glyphs, each marked by a different substance: ash, black salt, red wax, silver dust, and emptiness.
