Theres only one team who got to see the onepiece and what happen to the void century and that is the roger pirates.
No matter how you look at it, it seems like dragon is a deep person, he didnt just formed the revolutionary army just for a change he knows something a much deeper and its connected to what happen to the void century and this affects other people. Think about it he declared a war to the celestial dragons not the world goverment.
So this is what i think. That dragon is actually a roger pirate. He was in edd war and he did change the weather that time it means he was strong as hell even back then. He also knew what the roger pirates knew in fact he probably got something from roger before roger died. Thats why Dragon was proclaim to be the most wanted man in the world not just because his strong but he also had the knowledge that roger and his crew had. Even garp cant stop dragon just like he cant stop luffy becoming a pirate.
