Deepsky Citadel is the lowest inhabited isle, and the dwarven capital in the Sundered Skies. The citadel is a floating fortress with many turrets, towers, and gun emplacements. There are also two huge chimneys belching the waste from the Factory into the void.
King Bloodaxe occasionally presents small amounts of earth to those who prove themselves great friends of the dwarves. It is among the rarest of samples in the Skies.
