The Iron-Duke

Appearance
The Iron-Duke is a heavily scarred dwarf encased in a suit of polished obsidian plate armor that is always covered in a fine layer of soot. His right arm has been replaced by a massive mechanical prosthetic that constantly vents steam. His voice is a deep rumble that sounds like grinding stone.
Personality
Hawkish, aggressive, and fiercely patriotic, the Iron-Duke believes that Steamfort's destiny is to rule Aethervale through industrial and military superiority. He has no patience for diplomacy or "arcane nonsense," valuing only results and raw power.
Secret Motives
The Duke is obsessed with "reverse-engineering" the ancient power of the First Brood to create an ultimate weapon for Steamfort. He views the Obsidian Scale not as a religious threat, but as a source of experimental technology and draconic essence that he can harvest to fuel his war machine.
Combat Tactics
A master of tactical warfare, the Duke fights alongside a squad of elite Iron-Guards. He uses a heavy Aether-cannon mounted on his mechanical arm to deliver devastating long-range blasts. In melee, he uses the arm to deliver bone-crushing strikes and can release a localized "Steam-Burst" to blind and burn anyone in his immediate vicinity.
