An abandoned dwarven vault now infested with myconids

The Gilded Overgrowth of Karak-Vazul

The air in the deep vaults of Karak-Vazul no longer carries the dry scent of iron and stone. Instead, it is heavy with the cloying sweetness of rot and the prickle of microscopic spores. Thick, translucent mycelium filaments weave through the gaps in the massive granite doors, pulsing with a faint, bioluminescent violet light. Where once the rhythmic hammers of dwarven smiths echoed, there is now only the wet, rhythmic thrumming of a hive mind, a fungal heartbeat that resonates through the very bedrock. Deep within the vault, the gold has not been stolen; it has been repurposed. Piles of silver coins are fused together by sticky white growths, serving as nurseries for glowing mushroom caps. The armored remains of the vault's original protectors still stand at their posts, though their plate mail is now bursting at the seams with puffballs and shelf fungi, their movements jerky and puppet-like under the direction of the Mycelial Sovereign.
