Grim kingdoms: Lost structures & ruins Vanilla Edition

by HardWater

Grim Kingdoms: Lost Structures & Ruins - Vanilla Edition places a large set of hand-built castles, citadels and ruins into generated worlds, each one filled with vanilla mobs.

What it does

The mod generates a large set of hand-built structures, including forts, citadels, castles and ruins, across the world. Each one is populated by vanilla mobs such as pillagers, vindicators, zombies, skeletons (including wither and stray variants), wolves and feral white rabbits. The Vanilla Edition version removes a set of hidden unique vanilla items, so players who expect those items will not find them.

The mod is published for Fabric, Forge, NeoForge and Quilt, and a data pack build is also available for server platforms. Only the server has to run it: players may add it or join without it. Files cover 1.19 – 26.3 across 27 release versions, and the latest file for every loader is 2.0.0+mod for 26.3. The code is released under All rights reserved, so it is not open source.

Key features

  1. Close to 100 structures

    Roughly one hundred handmade forts, citadels, castles and ruins are added to newly generated terrain.

  2. Vanilla mob inhabitants

    Structures are occupied by pillagers, vindicators, zombies, skeletons, wolves and feral white rabbits.

  3. Removed hidden items

    The Vanilla Edition drops a set of hidden unique vanilla items, so their drops and locations are absent.

  4. Fantasy and medieval themes

    Structure designs follow fantasy and medieval architecture, varying the look of ruins across biomes.

Use cases

Exploration on a new world

Players exploring fresh terrain can find castles and ruins to visit and loot.

Server owners can add the structures to a shared world without requiring players to install anything.

Who it’s for: Players who want more fortifications and ruins in vanilla-style worlds, and server owners who want structure generation that clients do not need to install.

How it compares

Full comparison

Simple Structures: Caves is server-side friendly and released under the MIT License, with files for 1.19.2 – 26.3 on the same four loaders. William Wythers' Overhauled Overworld is also server-side, and its files cover 1.20.1 – 26.3, but it is released under a Creative Commons non-commercial, no-derivatives license. AdoraBuild: Structures needs both sides, and its files run on Fabric, Forge and NeoForge only.

Questions

Does Grim Kingdoms require a specific loader?

No. Files exist for Fabric, Forge, NeoForge and Quilt, so any of those four loaders can run the mod, and a data pack build is also available.

Do players need the mod installed?

Not necessarily. It is required on the server and optional for players.

Does the Vanilla Edition change any items?

Yes. It removes a set of hidden unique vanilla items, so those items will not appear in the world.
