Crimson Foundry

Crimson Foundry is an expert skyblock modpack where GregTech CEu, Create, Blood Magic, and Ars Nouveau come together in one demanding progression.

Begin at the Crimson Arrival Hub, choose your starter island, and turn limited resources into a sprawling industrial empire. Progress comes through careful planning, complex manufacturing, and automation. Every new machine is an achievement—and every production line prepares you for the next challenge.

With over 2,800 custom recipes, even familiar crafting takes a different path. Work through manual processing, resource generators, sieving, kinetic machinery, blood rituals, and arcane manufacturing before climbing GregTech’s voltage tiers from steam through UV.

Your foundry includes:

• 772 quests across 48 chapters, with illustrated guides, progression paths, and recipe access.
• Eight distinct starter islands you can reshape into your own factory.
• Nine resource generator multiblocks, with ten frame tiers offering up to 512× output.
• Custom components, textures, recipes, and menus built for Crimson Foundry.
• Multiplayer support with a shared hub, team islands, /home, /back, /tpa, and automatic playtime ranks.

The challenge is building an industry that can sustain itself. Keep earlier production lines running, expand your infrastructure, and bring technology and magic together to forge the Heart of the Crimson Foundry.

Industry. Blood. Source. How far will your foundry grow?
