Marius was born in Rome in 30 BCE. He was the son of a Roman patrician and a Celtic slave.

When he was mortal he travelled most of the land, writing a travelogue and the history of world, he became a Roman senator. Some time during his life he went to war, as his family wished, but he decided it wasn't for him, he preferred a life filled with books and all things of beauty and art.

At the age of 40, when he was sitting in a tavern recording his travels he was encountered by a man from the north -- a druid.

After small conversation and a short while later, he was abducted by druids and taken away to caves in Gaul and keep prisoner. He was prepared to be given to the 'god of the sacred Grove' an ancient vampire who resided in the sacred oak. He was extremely burned, black as charcoal, hurt and weak. It was there that Marius was made into a Vampire. Afterward, he was told by his maker to go to Egypt and find Those Who Must Be Kept -- the ancient Vampires, Akasha and Enkil.
