Original Mod: https://www.curseforge.com/minecraft/mc-mods/perthros-structures
Perthro's Structures plans to add a variety of new structures that enhance the exploration experience in a way that attempts to not be too invasive. However, the original had some very out of place structures such as the storage complex, which have been moved to this mod! This version only has 2 structures, 1 being a major structure and then 3 smaller structures.
STORAGE COMPLEX
An abandoned storage unit situated in the depths of the frozen wastelands. Valuable materials are abundant, but so are mobs. Can be found in snow plains, ice spikes, snowy taigas, snow slopes, and frozen peaks.
