Nyoldarria
by Roxanne
Nyoldarria is a survival-centric NeoForge expansion for 1.21.1 that adds a cold, sandboxed world with its own gameplay, and it needs RXB-Kit to load.
What it does
Players must find and eat the right foods to stay alive, since there is only one source of sustenance and the rest of the survival loop depends on it. Staying near the world centre keeps the character warmer, while going away from spawn brings colder weather, stronger enemies and better loot from crates. A scanner shows the temperature and other vitals, and an area where the temperature drops below 10 degrees begins to freeze the player until the character faints.
Heat is handled through a Heat Furnace, which gives passive warmth when powered by coal, and armour grants Insulation that can be improved with insulation blocks placed around a shelter. Storms envelop the land, bringing more enemies and colder, harder-to-see conditions that push survivors to seek cover. Some items follow physics-object behaviour, so they can be shoved around the way objects are in Source Engine games.
Nyoldarria is an early access project by Roxanne, and the author notes that much of it may still change. It requires RXB-Kit, runs on the client and the server together, and is released under All rights reserved, so it is not open source. Files exist for 1.21.1 only, and the latest NeoForge build is 0.1.009, published on 2026-09-06.
Key features
Heat and shelter
A Heat Furnace warms nearby players when powered by coal, and insulation blocks around a shelter make the warmth last.
Freezing and vitals
Cold areas drain the character until it faints, and a scanner reports temperature and other vitals.
Storms and enemies
Storms raise the number of enemies and reduce visibility, while the cold and enemy strength grow with distance from spawn.
Pre-Singularity travel
A bottle of an odd substance, used with a Teleporter, sends the player to a past timeline of the world.

Use cases
Survival playthroughs
The survival loop of food, heat and shelter suits players who want a harder, more immersive run than vanilla.
Shared servers
Because both sides run it, a server can host the whole experience for every player who joins.
Who it’s for: Players who want a survival world built around cold, food and shelter, and server owners who host a shared survival game with the mod installed on both sides.

What the author says
Do note that this is in early access, a lot of things are subject to change and this is only a small slice of what this mod aims to be, which is basically, a whole new different game! (Very ambitious I know, but I’ll try my best! This mod is purely a passion project and will continue getting new content for a long…
