Guildmasters' Guide to Ravnica by Jeremy Crawford, Robert J. Schwalb, Ben Petrisor, Mike Mearls, Chris Tulach, Ari Levitch, James Wyatt

4.0

Guildmasters' Guide to Ravnica by James Wyatt is a great supplement for those DMs who either want a pre-built world, or some mechanics and extra personality to add to their own homebrew. The Magic: the Gathering setting is quite layered with a deep history but for many, myself included, the world isn't quite what we want for our campaign. Thankfully, this book also brings a myriad of awesome mechanics and ideas that can be easily translated into any homebrew. It helps to define the layers of guilds and factions, allies and adversaries, which can add a ton of intrigue to the subplots throughout one's world.

TL;DR: Great Magic: the Gathering world setting for those that want it. Even better to help lay the foundation for guild and faction creation for those wanting to homebrew their own political and cultural landscapes.
