The ground beneath the trio's feet was treacherous, an unpredictable mosaic of glossy obsidian that reflected distorted images of the cavern above. Cracks ran like veins through the terrain, their edges razor-sharp and glowing faintly as if the magma beneath was reluctant to fully relinquish its heat. Walking was a precarious task; every step required calculated precision to avoid the shards of obsidian that jutted from the ground like deadly thorns. The jagged ridges created natural barriers and narrow paths, forcing the trio to move with both caution and ingenuity.
