In the 20 years since Wizards of the Coast bought Dungeons & Dragons, they’ve never truly explored the one most obvious crossover between it and their other most popular product: Magic: The Gathering. For years, the answer was always that they were two separate products which existed in their own separate worlds.

That’s not true anymore. A product listing went live Sunday on Amazon is showing off Guildmasters’ Guide to Ravnica, a Dungeons & Dragons setting supplement for playing on Ravica, one of Magic: The Gathering’s most enduringly popular settings. Today, Wizards of the Coast confirmed that the book will release on November 9th in game stores, November 20th to the public. Ravnica is a city the size of a world ruled by ten scheming, competing guilds, each of which represents a combination of two of Magic’s colors of mana and regulated by powerful, world-spanning magic called the Guildpact. Wizards of the Coast had previously announced that a new Dungeons & Dragons setting book would be announced today on a livestream. Previous announcements gave that date as the 22nd, a possible reason that the product listing on Amazon went up early yesterday.
