Realm of Winter

A frozen realm where it is necessary to build a armour from wool to stay warm Fires also help The entire realm is frozen Includes oceans frozen over where strange icy creatures lurk in the cold depths Vast icy mountains and large caverns filled with ice and maybe new mobs frozen in the cold that can be broken out In the snow covered plains strays and other mobs lurk I'm thinking a dangerous mob that can hide under the snow and makes a strange noise when about to attack Also in the heart of this frozen wasteland is a Winter Hydra or some other appropriate boss A frozen castle would be a fun dungeon and perhaps a villager like species lives sheltered from icy winds in there A new ore called icenite that would create a rnage of new items including frozen weapons which have an advantage in icy biomes in the overworld
