Ignore the map preview.

This mod starts you off on an empty world, where Voidcraft is your main, and often only, way to get resources. You begin on an island in the middle of the vast void ocean with nothing but a voidshed, a crude building capable of elementary voidcrafting. The voidshed is enough to get you started, but it tends to spit out a disgusting slime that isn't good for much but fuel. You'll need to craft some stone and metal, build more infrastructure, start producing science, build some better voidforges and voidworks, and make landfill... lots and lots of landfill. You'll also need to brush up on your hydromancy, because whatever that ocean is, it isn't water.

This mod makes some changes to the tech tree to make this all work halfway reasonably. Landfill is acquired very early, and the cost of landfill has been reduced back down to 20 stone. The time it takes to voidcraft landfill has also been reduced from 60 seconds to 40 seconds. In Space Age, the cost of foundation and ice platforms have also been reduced. You'll need these because the other planets are also just islands in the middle of nowhere. Of course, since you can voidcraft anything just about anywhere, you might not actually have to visit for a while. If you really want to avoid leaving your starting planet, there is also an option to remove almost all surface condition restrictions.

Just like Voidcraft itself, I am still tweaking the balance and recipes. This mod requires a new game; in an existing game, it'll start generating chunks of nothing but ocean as you expand your map, which will... sort of work... but it will look strange.
