About this Mod

Left Forgotten

Left to fade away into distant memories

Competitor to Alpha Below/The World Below

Based on a tweet by @SlimerSlimy and Minecraft Alpha 1.1.2_01 (the actual version, not the fangame)


Why?

Mainly just to play around with parts of True End's code for soon coming Fabric+Forge port (and because I was bored)

Description

Left Forgotten adds a Alpha-like dimension accessible by blowing a hole in Overworld's bedrock layer wherever there is Brittle Bedrock.

It is dark and abandoned, untouched in years and shadowed by the overworld above with no mobs or anything alive other than some vegetation.

This is not a horror mod, but rather a adventure and decoration mod. Just plain old Minecraft Alpha 1.1.2_01 with a few remnants of player activity from many years ago.

    • Accessible by going into the Overworld void
    • Escapable by either attempted death or flying up to the bedrock ceiling
      • Leaving via death will cancel the damage and just teleport you to your spawnpoint

      • Yes, there are Farlands
  • "Old player activity" features

    • +A chance to get an unused track "Droopy Likes Your Face"
    • +A chance to get screwed by music disc 13

Dependencies and Mod Compatibility

  • Left Forgotten requires Architectury API (and Fabric API on Fabric)
  • Left Forgotten recommends you install Polymorph
  • Left Forgotten is not compatible with True End due to very similar/duplicate codebases.

When newer Minecraft versions?

With version 1.1 Left Forgotten will update from Fabric+Forge 1.20.1 to:

  • 1.21.1 Fabric & NeoForge
  • (1.21.6-)1.21.8 Fabric & NeoForge
  • 1.21.11 Fabric & NeoForge
  • 26.1.2 and onwards Fabric-Only

REMEMBER! MOD DEVELOPMENT TAKES TIME! :D

How long will this be kept updated?

Probably for very long like my other projects.

Frequently Asked Questions

Left Forgotten server crashes on startup – what to do?

Most common cause: wrong fabric version or insufficient RAM. Check the server log (latest.log) for "OutOfMemoryError" or "Mixin" errors. With Mado Hosting: ensure at least 4 GB RAM is allocated and the loader matches the mod version (1.20.1). You can switch loaders with one click in the panel.

Is Left Forgotten compatible with fabric and forge?

Left Forgotten officially supports fabric, forge for Minecraft 1.20.1. Note: Forge and Fabric mods are NOT cross-compatible – pick one loader and stick with it. The Mado dashboard automatically detects incompatible loader combinations.

Server lagging with Left Forgotten – how to optimize performance?

Recommended RAM: 6 GB (per 5 players). Use /spark profiler to check if Left Forgotten consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge. With Mado Hosting, your server runs on NVMe SSDs with dedicated CPU cores for minimal latency.
