In 736 AUC, Caius Lumis Juventus, Roman inventor extraordinaire, demonstrates the most powerful steam engine ever built. Caius had been a student of the ancient Greek sciences, and had learned of the simple uses they had put the power of steam to in the old days. Jove's Thunderbolt, the engine that Caius Juventus built, was capable of pulling a carriage with three heavy men for miles. His designs revolutionized Roman society.
