Deeproot Sprawl

Deeproot Sprawl sprawls across a labyrinthine series of colossal caverns, illuminated by bioluminescent fungi, hanging lanterns, and the restless activity of its cosmopolitan denizens. Packed bridges span dizzying chasms and whispering rivers, bringing together merchants, refugees, tunnel farmers, and artificers. The city never truly sleeps, its echoes a living pulse beneath the mountains.
