I doubt there aren't any more DS around, except for Natsu, Gajeel and Wedy, everyone else came out from nowhere or had Dragon Lachryma implanted. Anyway theres a LOT of powerful mages there, all the guilds, Jellal's group, the council is there and who knows who else. If 10% (?) of humanity was able to survive against thousands of them, I see no reason as why the strongest mages in Fiore (or the world?) wouldn't be able to survive against just 7 of them
LOL at that big ass flame dragon. Obvious food for a beat up Natsu. These dragons is probably gonna get run over by the friendship train with all the guilds combining all their might. Being a dragon slayer wouldn't be so special after all after this mayhem.
