by Gourmandd

On Ancient Ground-Core is a NeoForge library mod for the Ancient Ground modpack, supplying the shared content and registries that the modpack's add-ons build on.

NeoForgeClient and serverEuropean Union Public License 1.2Open source1.21.1

What it does

The library is centered on TerraFirmaCraft and written for the Ancient Ground modpack, which is built on TFC and the Pastel integrations. It adds the essential content the modpack needs, including a snow shovel, glass pane molds, a wrought iron bucket, and new ores such as bauxite, galena and anthracite. A clay type registry adds four clay types with their associated items.

Because the library depends on eight other mods, it cannot run alone. ArborFirmaCraft (AFC), Architect's Palette [Fabric], Caupona, Create, Create Big Cannons, Quark, Shutters, Spectrum and TerraFirmaCraft must all be present. Integration content covers fruit trees, crops, bushes, wood type blocks, sewing tables, looms, shelves, metal types and rock types, and the library works with the Stuff Additions integrations.

The library is open source under the European Union Public License 1.2, and its source code and issue tracker are public. It is published for NeoForge only, for 1.21.1, and the latest file is version 1.0.6, released on 2026-07-25 on the alpha channel. Client and server both need it, so the server and every player must install it.

Key features

  1. Snow shovel tool

    A snow shovel is added as a tool for clearing snow and ice in the modpack's world.

  2. Glass pane molds

    Molds for glass and glass panes are added, so glass can be shaped through the modpack's crafting chain.

  3. Wrought iron bucket

    A wrought iron bucket is added for carrying fluids in the modpack.

  4. New ores and clay types

    Bauxite, galena and anthracite ores are added, along with a clay type registry that adds four clay types and their items.
