This new offer presented nearly two dozen Mythos investigations in many eras from the open-license Cthulhu Eternal game line produced by Cthulhu Reborn. Compatible with your favorite Lovecraftian percentile-based systems, the Eternal open rules set, based on Mongoose Legend and the Delta Green RPG, is free under the Open Game License.
