The campaign is set in the world of Ravnica, during the phyrexian invasion, and a few years after the Nicol Bolas battle with the Gatewatch. Once again the various guild members will have to overcome their previous prejudices and fight shoulder to shoulder to fight the impeding consumption of their world.
While each guild will spending nearly all its resources battling on the main front, each guildmaster has been tasked to select a few specialist members to join in on more secret and covert missions, hoping to cut the head off the snake.
Perhaps you were chosen for your fighting prowess. Maybe you bribed your way in. Maybe your guildleader thought it would be funny to send you. Either way your success could very much turn the tide of the war.
While there may not be much time for rest and relaxation. Characters can expect that various missions will take them away from the battle lines and deep into the heart of the still bustling city where they may be required to solve problems without their fists (Sorry Gruul players).
