MoP I'm not trying to be a nitpicky bastard but if the destroyed city is West City like I'm assuming then there's no Dragon Ball there. Shitagi had the Four Star and the Dragon Radar at Capsule Corp but got both away from the city prior to the destruction. If there was a second Dragon Ball in West City then Shitagi would have known about it without question. Also it can't really be any other destroyed city since so far West City is the only one to have suffered an attack of some sort.

Granted at the end of the day it's Heald and Blade's call since it's their RPG. However I felt these were things that needed to be pointed out before you proceed as a second DB in West City could confuse people.
