Fort Duke guards the port.

The city of Burgh in many ways, is representative of the Steel League.

Svarozic. A giant lives at the heart of the city. Inhabiting the largest steel mill is a man over ten feet tall, apparently made of steel, himself. It is unknown where the giant came from, whether he is some fallen god or titan, or just the member of a lost race is unknown, perhaps even to the giant himself. Svarozic, as he's called, works tirelessly and seems impervious to heat. He does not seem to sleep, but at times goes still and appears to be at some sort of rest–sometimes for as much as weeks at the time. Luckily for Burgh, Svarozic accomplishes enough when at work to keep them ahead in the manufacture of steel. The other steelworkers–many dwarven refugees –see “their” giant as a source of civic, and professional pride, and tell tall tales about his exploits.
