Ravnica is a sprawling cityscape so vast that it covers the entire world. This mosaic of Gothic spires, cobblestone plazas, dangerous slums, and ancient ruins is home to races and cultures of incredible diversity. From the smallest insect crawling through the Undercity to the majestic dragons circling on the horizon, an immeasurable population resides in this metropolis. A traveler could spend a lifetime exploring the open-air markets where anything is for sale, the awe-inspiring cathedrals that dominate the horizon, or the gilded museums showcasing archeological finds from Ravnica's ancient past. All walks of life can be found in this city, and there is a sharp contrast between places like the austere and immaculate Azorius Senate and the chaotic slums of the have-nots. Back-alley deals, crime syndicates, and the black market thrive on Ravnica, but the true power resides with the guilds.
