If you've played skyblock you may know you always start with a tree or at least a single block right?
well with Void Block you can start with only the void and get stuff from there.
With the mod installed and with the default config settings you will not be able to fall thus stopping you from just falling into the void as soon as you spawn in, in order to get dust you just need to right click the air and you will get some dust and you can craft the dust into plant matter then into void blocks and leaves.
TO BE CLEAR, The void will still kill you without some other mod that prevents that
The void block block in very special because it can be placed under you by just right clicking with it in your main hand, placing your first void block will return your ability to fall so make sure you dont fall of your new block.
the mod doesn't add world gen only the blocks, items and the way to get them so you will need more mods to use this to its fullest.
In order to use this mod in a pack you will need to use, at minimum, something like Kubejs to add some way of crafting dirt to grow trees but feel free to use any mods that you think will fit with the idea of starting from the void.
