Ravnica

Ravnica is a block that consists of three expert-level expansion sets: Ravnica: City of Guilds (October 7, 2005), Guildpact (February 3, 2006), and Dissension (May 5, 2006).

Much power in Ravnica is held by the ten "guilds", political factions that each represent a combination of two of . 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.
