Rumble in the Rubblebelt

Publisher's blurb: A 2-4 hour Ravnica adventure for 1st-3rd level characters. A Gruul raiding party steals a powerful Izzet magical device, putting all of Precinct Four in danger. If the ignorant Gruul raiders accidentally trigger the device during their drunken Rauk-Chauv revelry, it will vaporize the entire precinct. Can a small group of heroes enter the rubblebelt of the Red Wastes and steal back the device before the Gruul destroy thousands of Ravnicans?
