Ravnica is a Magic: The Gathering block that consists of three expert-level expansion sets: Ravnica: City of Guilds, Guildpact, and Dissension. Following in the tradition of other Magic blocks, Ravnica takes place in a plane of the multiverse that was previously unexplored in the game's backstory. The world of Ravnica is an ecumenopolis, a vast city that covers the entire surface of its planet, and is home to a diverse assortment of sentient races. Much power in Ravnica is held by the ten "guilds", political factions that each represent a combination of two of Magic's five colors. The mythology of Ravnica is loosely derived from Slavic folklore, and the character names reflect this. This plane was revisited in the Return to Ravnica block, and the Guilds of Ravnica, Ravnica Allegiance, War of the Spark, and Murders at Karlov Manor sets.
