World

World generation, biomes, caverns, magma, aquifers, weather and climate.

World generation decides the history your fortress inherits before the first pick strikes.

Biomes decide climate, plants, animals, evil weather and fortress difficulty.

Caverns open resources, threats, spores and pathing complications.

Magma turns fuel problems into engineering problems.

Aquifers are either a nuisance, a water source or a fortress-ending misunderstanding.

Weather ranges from scenery to evil rain that rewrites your survival plan.
