Description
***7/14/2025 This mod collection is no longer being updated. Permission is granted to all modders to remix, recreate, and reuse. Everything I have created is yours. May it serve you well. ***

Welcome to the Call of Cthulhu expansion project for RimWorld, the Rim of Madness.

Mission Statement
This will be a series of themed mods inspired by H.P. Lovecraft's works. I will expand the RimWorld experience by implementing spine-tingling cosmic horrors, themed objects and apparel from the late 18th until early 20th century, sacrificial cult gameplay, and horrific events.
