Catastrophe, first part: The planet of the Nomads burst.
Catastrophe, second part: A few survivors drift on rocky islands through space and time.
Anyway, the catastrophe has its good sides as well: 1.) A fascinating world in airy spaces was created. 2.) The game character you choose - mysterious Susie, clever John or strong Goliath - has survived. 3.) You have a task: Destroy the originators of the catastrophe and other creeps. 4.) Get ready for the final countdown. With magic items, you can transform your island to a battle giant teeming with weapons. You also use these items to produce heavily armed flight devices for the search of further artefacts and in order to gain raw materials for energy supply.
There's heaps to do. Snap to it!

Project Nomads is a 2002 computer game by Radon Labs released for Windows and macOS. It is set on the fictional planet Aeres, a world of floating islands which are the remnants of the planet from before it exploded. Few surviving inhabitants settle on drifting fragments of Aeres following its explosion. The player character is a nomad tasked with wandering across these islands, discovering mysterious artifacts and exploring the ruins of the long-dead race of Master Builders, a group of highly skilled and influential characters within the game's world. These characters possess exceptional knowledge and expertise in constructing and manipulating the floating islands that make up the game's environment. The only place to fall to is the Sea of Flames, the utmost depth of this new world.
