Gregnautics is a realistic hardcore tech-survival modpack built around TerraFirmaCraft/TFC, Create, Gregtech/GTCEu and Create Aeronautics inspired by TerraFirmaGreg/TFG
Create Addon organiser (Or CAO for short) makes create addons get sorted into the main "Create" tab in a style similar to create aeronautics, with tons of customisability.
Sky Archipelago adds a new floating-islands world generation. High degree of configurability, such as island density, sizes, Y-spawn heights, ocean or void and much much more!
