It’s hard to imagine why it took so long for a setting stuffed with mad science-wizards, demonic jesters and a ghostly mafia to find its way into D&D, but while Guildmasters’ Guide to Ravnica is undoubtably a blast from end to end it struggles to dive into the details that DMs need to run a living campaign.
The sprawling metropolis of Ravnica first saw light as a setting for the Magic. The Gathering card game, establishing a strong tone stitched together from steampunk and fantasy tropes. On its own this would be enough to set the world apart from the Forgotten Realms, the high-fa ntasy default setting of the current edition, but perhaps the most unique aspect of Ravnica is the titular guilds.
