THE DELTA RUNE

by Meowser

The Delta Rune is a Forge and NeoForge world generation mod, themed on DELTARUNE, that adds dimensions, blocks and items to Minecraft.

What it does

The mod is a fan-made DELTARUNE project for Minecraft. In its current state it adds dark worlds with new blocks and items, and a fifth dimension is planned to join them. Some areas are described as works in progress, and the author notes that an update is still to come.

Each world is built from placed blocks such as stacked concrete, planks and wool, arranged around a dark fountain. Earlier builds were a different mod, and the author is reworking the content. Installation needs no other mod, and the environment is client and server, so the server and every player must run it. The Delta Rune is published for Forge and NeoForge across five game versions, 1.20.1 – 1.21.11, under All rights reserved, which means it is not open source.

Key features

  1. Dark worlds

    Four dark worlds are included, each built around a dark fountain made from stacked blocks.

  2. New blocks and items

    The mod adds dozens of blocks and a set of new items for the DELTARUNE areas.

  3. Fifth dimension

    A fifth dimension is in development as an addition to the existing dark worlds.

  4. Named areas

    Areas such as Lost World, Failed Sanctuary and Field Hopes Dreams each have their own layout and block palette.
