Overview

@The Pillar Warrens lie beneath the @Upper Galleries and once formed the living heart of @Gloomdeep . This labyrinth of colossal support columns held homes, workshops, and aqueducts that sustained the city. When the Corpse Plague spread upward from @The Vaults , the warrens collapsed into a flooded maze of ruin. Today, @The Ashen Vigil reach ends at its upper edge, beyond which the city is lost to darkness.

History

Foundation of the City: Built around massive stone pillars that supported the upper galleries, each hollowed out and inhabited by thousands of goblins.
Collapse and Flooding: When the Veil ruptured, flooding from the aqueducts drowned entire districts, turning them into echoing caverns filled with drifting corpses.
Abandonment: The goblins’ defenses failed quickly. Entire families vanished into the water tunnels, never to return.

Description

The warrens stretch endlessly beneath the galleries, filled with shattered bridges and waterlogged halls. Stone pillars rise from the depths, many cracked or fallen, leaving great gaps where the ceiling has collapsed. The air is damp and heavy, lit by flickering light from distant sunstone veins reflected on black water.
