Ferrovax is a dragon. He is also known as Mr. Ferro. He first appears at Bianca's Ball in Grave Peril.


Ferrovax was present at Bianca St. Claire's masquerade party; he was wearing the authentic armor of a Roman centurion and was exhaling smoke while holding an unlit cigarette.[1]

Ferrovax is the eldest of his kind, the strongest of the Dragons. He displays immense magical power with only a wave of his hand, and claims there's power with the use of someone's name.[1] There also seems to be something in the Lore that says not to use a name other than his full name.[1]

In the seriesEdit

Grave PerilEdit

Main article: Grave Peril

In Grave Peril, Harry Dresden met Ferrovax at Bianca's Ball for the first time. Michael pointed out to Harry that he was a dragon. When Ferrovax told Michael and Harry to call him Mr. Ferro, Michael refused, suggesting he just call him Ferrovax. Ferro said that Michael knew something of the Lore, at least for a mortal.(reference needed)

When Harry snapped a correction at the creature for getting his name wrong, he coldly suggested Harry not try to find out what he could do by speaking his name and making an effort. When Harry called him a bully, Ferrovax waved his hand and crushed Harry to the floor.(reference needed)

Michael informs Ferrovax that he slew the dragon Siriothrax, to which the dragon states:

So you are the one. I thought you'd be taller.[1]
Then suggests the knight should be more humble and perhaps get a gag for Harry.(reference needed)

Later at the Ball, on behalf of Bianca St. Claire, he was handed a gift by a hooded figure later identified as Cowl[2]—that he considered impressive.[3]

Skin GameEdit

Main article: Skin Game

In Skin Game, Ferrovax has a vault with his name on it, FERROVAX-00010002, in the Capristi Building, John Marcone's mob bank, indicating he has vested some of his fortune, or possibly items, with the crime lord.[4]


It is possible that Ferrovax is also infected by the Outsider, Nemesis, with the gift presented to him at Bianca's Ball, as the Leanansidhe was affected by the Athame she was given at the party.[5]

Word of JimEdit

According to Jim Butcher, Ferrovax will appear again in the final books of the series.[6]

Quote Edit

"Don't tempt me to show you what I can do by speaking your name and making an effort, mortal. suffice to say that you could not comprehend the kind of power I have at my command. that my true form here would shatter this pathetic gathering of monkey houses and crack the earth upon which I stand. If you gazed upon me with your wizard's sight, you would see something that would awe you, humble you, and quite probably destroy your reason. I am the eldest of my kind, and the strongest. your life is a flickering candle to me, and your civilizations rise and fall like grass in the summer."[1]
