Lair
Lair Actions
On initiative count 20 (losing initiative ties), the creature can take a lair action to cause one of the following effects; it can't use the same effect two rounds in a row:
- Digestive Surge. At initiative count 20, the lair's interior shifts; 20-foot cubes of acidic slurry erupt in the corridors, creating difficult terrain and dealing 2d6 acid damage to anyone standing in them.
- Walls of Slime. The walls ooze inward, forming temporary barriers that force creatures to move through narrow channels, granting the City Devourer advantage on attacks against those trapped.
Regional Effects
The region containing the creature's lair is warped by its magic, creating the following effects:
- Within 6 miles of the lair, every building subtly shifts as if breathing, making sleep difficult for inhabitants.
- The ground sighs with distant digestion; minor tremors shake the area weekly.
- People within the radius feel drawn to the city, as if lured by a whispering maw.
If the creature dies, these effects fade over the course of 1d20 days.

Lore & Description
Appearance
A city-sized mimic that has grown to consume the very metropolis it inhabits. Its exterior resembles stone, glass, and steel streets that appear like a living city cutout: towers, boulevards, and plazas form a living skin that can reconfigure itself to trap prey. Its maw opens along a wide breach, lined with teeth of rusted iron and cracked glass, devouring inhabitants and redirecting their remains into its vast interior digestive chambers. The city consumes people slowly, converting them into nutrients that sustain the living metropolis. It only moves at a glacial pace, dragging districts along like a slow tide, and its breath dissolves brick and bone alike. It dreams of consuming an entire world, one metropolis at a time.
Behavior & Origins
Ancient rumor tells of a city that lured travelers into its own streets, only to digest them and absorb their life. Over centuries, the city grew, its walls thickening into arteries, its roads becoming intestinal corridors. It now sits as a living organism hidden within the urban sprawl, a city-sized mimic that devours anything it calls home. The inhabitants who survive have learned to keep their distance; to approach is to be swallowed and rearranged into nourishment for the city itself. Some say the mimic is a protective form for a long-dead civilization, a doomed city that became a predator.
