Mod «MorrowRim» for Rimworld (v1.1)


Adds in the ashlands and blighted ashlands biomes.

Ashlands is based on a combination of regions from Morrowind. It contains highly fertile soil that supports a thriving ecosystem. Frequent ash storms make settling here somewhat challenging.

Blighted ashlands is based on a combination of the ashlands and red mountain regions from Morrowind. The soil here is of low fertility, with large areas effectively unfarmable. There is little plant variety, with none of it being edible. Animals are less common and frequently driven mad by blight storms, which also cause crop blights.

Adds in new weather for the two biomes.

Ash storms are the most frequent of the new weather types. They reduce sunlight, movement speed and ranged weapon accuracy. They will also damage vanilla wind turbines and plants that are not adapted to the area or sturdy enough. Pawns that are not adapted to breathing in ash storms will suffer buildup whilst outside. This can result in permanent lung damage, and eventually death. This can be avoided by remaining inside or wearing clothing that completely covers the face.

Blighted rain and blight storms are less common, with greatly increased commonality in blighted ashlands. These can drive wild animals mad and inflict crop blights.
