SevTech Ages of the Sky Modpack is a massive modpack focused on long-term progression and exploration. You start with almost nothing-no map, no HWYLA, and only a few items and recipes. Your goal is to advance from the Stone Age all the way into space! The pack uses the vanilla advancements to guide your journey while keeping a sandbox experience. As you progress, you unlock new ages, mods, items, and blocks. This modpack is fully multiplayer compatible.
