The slave pens stretch before you, a tangled cluster of iron cages forged from dark, jagged bars etched with faintly glowing runes. The sickly green light they emit casts warped shadows onto the uneven cavern floor, slick with patches of moss and compacted mud. Chains dangle from ceiling hooks, their manacles clinking faintly as they sway. Figures slump within the cages, their distorted silhouettes shifting against the pale light. A crude watchtower rises above, its spiked platform barely supported by crooked beams, while a yawning pit lined with jagged stones looms in the corner, its edges marked with dark stains. The acrid smoke of a nearby brazier mingles with the hum of runes and the metallic rattle of restraints, every detail reinforcing the oppressive design of this grim place.
