"We've got the seven seals of the apocalypse, as each of these seals breaks you get one step closer to Armageddon and the world ending completely, which is what the Romans thought was happening. Attila the Hun was death on a horse, and you didn't really want to get involved"

"Going back to the religion, that's a really nice point because we are telling that story of the apocalypse as seen through the eyes of the Catholic factions. So we are focusing on west and east Rome, and how they literally thought the world was going to end because of the climate change and how Attila was this god coming to punish them for their sins."

Some quotes from an interview. How much truth is in this?
