IkarusOnline

The city's districts are divided up into what are known as Cantons, large disks about 280 blocks in diameter, each with their own distinct color scheme and architectural theme.

Surrounding all of Ikarus are iconic blimps and hot air balloons, some of which store their own secrets, for those who can access them...
