The Guildpact has kept Ravnica stable for thousands of years. But with ten guilds vying to become the dominant force on the planet, there's always a chance that things will break down. Guildpact continues the story of this massive city, and introduces players to three more guilds. The Gruul ravages the streets. Teysa leads the Orzhov Syndicate to "cleanse" them. And Agrus Kos doesn't give a damn.
