Lucius visited the Caecilius family the day before the eruption of Mount Vesuvius to get part of a marble energy converter designed by the Pyroviles from Lobus Caecilius. Under the direction of the Pyroviles, he collected the pieces to build the converter inside the heart of Mount Vesuvius. It would convert the population of the world into more Pyroviles. He was involved with the Cult of Vulcan. (TV: The Fires of Pompeii)
