Stratospherical Expansion Mod is a mod which completely overhauls the overworld generation to be made of sky islands. It also features completely reimagined vanilla biomes. Additionally, there is a dimensional version of this mod. It separates this into another dimension instead of overriding the oeverworld. To enter the dimensional version of this mod, you must fly to Y420 in the overworld. Its features are more limited with overall simpler generation. To return, you just fall into the void of the stratospheric dimension.
