About this Mod

Did you wondered how nether gonna looks millions years later?

This mod show exactly what will happen!

New dimension can be accessed by portal, its made from frozen lapis blocks and activated with unusual lapis nugget.
The portal

All items/blocks from mod spawn in cold nether, but some of them can be crafted using packed ice or can be get using trades from villagers.

This dimension is very dark, so bring torches or night potion vision to see it, but if you want a challenge, you can try survive spawning in dimension without items!
Cold valleys

Most often blocks in cold nether icy stone and icy granite. Icy stone drops normal stone and its only spawns in cold valleys or frozen overworld caves. Most often liquid in dimension is liquid nitrogen it damages 2 hearts/seconds.

Dwarf pine - new type of tree, you can get sapling smelting frozen pine sapling, that drops from frozen leaves of snowy bushes, that rarely spawn in warm valleys and it can only be grown on frozen grass.

Frozen piglins spawn in this dimension, but only food resource is blue berries since piglins drop only ice knife, the berries are rare and spawn in warm valleys. Blue berries have 4 stages (but 2 stages if you playing before 1.2 update). You can use bonemeal to speed up blue berries, they grow only on frozen grass block too.

Ores spawn only is cold valleys biome, there spawn frozen iron, diamonds, lapis, but frozen lapis also spawns in overworld frozen caves. Coal in cold nether most rare ore, it only spawns in lava lakes that are very rare in this dimension.

In this mod have many structures, like abandoned houses. Small frozen house made of snowy bush materials and spawns in cold valleys. Small pine house more modern version of small frozen house, and spawns in warm valleys. Since 1.4.2 wells was added they spawn in warm valleys and have rarest block of mod - ice shard block.
