Eurosia

Eurosia was one of the great sky cities of Titanis. The home of the greatest shipyards and the greater part of the Titanic air fleets, it was ruled by a triumvirate call the Boread, formed of the Master of the Docks, the High Admiral and the Merchant Most Noble. It was the most militant of the sky cities, and survived the Colossus War in part by withdrawing the fleets to its own defence, abandoning their allies as lost. After the War, Eurosia became the centre of power for the Frost Giants.
Around the time of the Cataclysm, a group of Eurosian giants raided the supposedly allied ciy of Mecheri to steal one of the Autoforges maintained by the Fire Giants. This provoked a feud between the two cities which persists to this days, but gave Eurosia the military edge to hold its own against the City of Hammers.
When the technology which kept it aloft began to fail, millennia after the Colossus War, the Giants of Eurosia were able to save their city by ditching it in the Sea of Fate, where it floats, anchored against the currents of the Cataract with a multitude of massive chains. They expanded the remnants of the city with flotsam, supported on sky cells scavenged from the wreck or traded or stolen from nomadic sky mansions.
The platforms of Eurosia are a massive, robust structure, but incongruously bouyant. The giants of this raft city remain as militant as ever, launching periodic campaigns into the Donar Wastes in search of less parlous territory to call their own.
