The relic, cursed! The walls, shifting! Steeling my nerves, I dashed at the stones, searching for some hidden door or portal. In retort, the dungeon merely mocked me, undulating like a mirage and sliding into a new position. I was inside some infernal puzzle box. Hark! Light! Egress! I hesitated. Not without the relic in my hands. Not without some proof. And there, I spent the last of my will pushing back against the cavern's uncanny malevolence, petitioning, nay, commanding it to vomit up its prized victual. Safe in my holding bag, I made haste from that daemonic hollow.
