I for one, having recently read the entire Lovecraft Mythos, LOVE how much Robert E. Howard included it in his work, and hope to see more in the future!
An… “Age of Madness” perhaps??
Where you can take a potion/perform a ritual etc… and you can see things that aren’t visible in the regular world… or a venture into another realm etc… With the amount of material there is, and how much it is referenced, i feel it could pull from just about any of Lovecraft’s stories, and not stray too far from Howard’s vision. Just throwin’ it out there…
