This mod is the winner of ModOff 2, winning 1st place! For the best experience, make sure you have installed Optifine, or CTM (ConnectedTextureMod) or most of the visuals will not work.

It is also recommended you keep music, sounds, and ambient noises on. We’re giving you Glacidus Beta, which is what we originally created in a week during ModOff showing off the amount of hard work and effort we put into this. The mod is of course incomplete. Hopefully you become interested in what we truly to believe stunning in the future. Things are subject to change, keep in mind!

This mod is still in development and coming soon to 1.15.x or 1.16.x. Stay tuned!

📚 Introduction

Frozen world on top and underground lies a different story. A strange alien planet with bizarre structure and thought to be impossible living conditions for life. The further down you travel – the warmer it gets. Foliage and water can be found along with natural elements the deeper you go. This planet was once in an orbit in a star system however, it unfortunately fell out of orbit and is parting ways and traveling space. It’s atmosphere is very thin. The planet’s core is what provides the undergrounds warmth and it is considered habitable.

Layer 1 - The Surface


The surface is the first thing you will see once you enter Glacidus. It’s surface is extremely cold and the gravity is low. The surface is supposed to be medium to high in difficulty and 2nd to the most dangerous of all the layers. On the surface you will soon be able to discover abandoned ruins that you can explore and find loot. Natural generation will include large dead trees, dead Lumicia stalks. Frozen Antinatric Stone, and large bodies of Glacium. Wind ambient sound plays and loops on this layer.

The surface is invaded with alien mobs that are immune to this cold environment due to their thick rough skin. They live in holes they’ve created in the giant spikes on the surface and wander around bewilderedly. Another mob lives in Glacium and spits balls of Glacium at you and gives you Freezing Debuff.

Layer 2 - The Underground


Warmer than the surface. Dark, glowing, and vivid with life. Down here is the most habitable zone of the planet. You can find natural blocks such as, Lumicia, the name of all natural terrain grasses, dirt, and overgrowth such as mosses and vines. You can also find purple looking water down here. It’s color comes from its environment. Mobs are found down here and due to the living conditions for them, they are strange looking and aggressive-neutral and unstable – meaning, they can turn hostile for any given moment or if you simply attack them they will attack you. A deeper more cave like wind sound will play and loop on this layer.

Layer 3 - The Core


Final layer will be the last and most difficult and challenging player will discover. Bright, hot and is dangerous, with many deadly hostile mobs. Going down here unprepared, the player will not make it very far. Once you enter, you will receive the Heat Exhaustion debuff if you don’t have the proper armor. Hostiles of the layer will target once they spot you. There will be safe zones, like cave openings, or even your own blocks, to shelter yourself. Wood, leaves, cloth, will immediately start to burn anywhere you place down here, water will evaporate, and Glacium will turn into water, which evaporates. A raid will be found here.

Creating a Portal


Portal may change in the future since it is a little weird. You will need exactly 30 packed ice blocks and 1 glowstone block. Once you are done building the portal break the glowstone block.
