"The Howl of the Chimeras", a Victorian scenario for #callofcthulhurpg unlike any you've played before.

I realized this morning that my scenario "Without Warning" is less than 25 sales away from hitting Electrum level on DriveThruRPG, which would make it eligible for being made available as a print-on-demand booklet. A perfect single-session RPG scenario for a cold winter night! #callofcthulhurpg

Looking forward to playing and running games later today at the @illusionhorror.bsky.social. I've got #CallofCthulhuRPG and #DeltaGreen on deck.

Yes, I know, this is a ** HUGE ** shift from my regular weekly games of...Call of Cthulhu and Delta Green.

I'm a creature of habit, gimme a break.

Today's #MasksofNyarlathotep was quite interesting, because we're so out of the box now. A captive (pc) of cult just escaped by entering into a painting he did, while cats are invading Cairo.

There's trouble in Saint Augustine, Florida. PCs are split. One in hospital. One in jail. Three in ghoul tunnels. One lost at sea. They're now in deep doo-doo.
Did you play this adventure? How did it go for you? Was it fun? Did uou change anything?
