What Players Say!
“Cthulhu in a Castle is a highly immersive and thoroughly enjoyable luxury TTRPG experience. They have thought of nearly everything, from GMs, Discord, character creation, and on-site assistance and tours of the beautiful venue to catering and much more! I would recommend anyone who can squeeze this into their schedule to do so; I had an absolute blast!”
— Austin“A weekend of insanely fun and intense gaming that you can't easily replicate at home or at a convention.”
— Rick Meints, President of Chaosium“Go with like-minded friends ready to spend most of the day on the campaign if you can, but even if you go alone, you'll likely meet new people just as excited about playing as you are!”
— Kevin“Our GM (Keeper) was stellar, both entertaining and deft at managing the pacing and engagement in the game. It was fun that most players and the Keeper did a bit of cosplay too. The event really had this 60-year-old man feel like he was reliving the glory days of teenage RPG games with his friends.”
— Bradley“Thank you for putting these events together. I can't express how meaningful they are to me. It's so much more than playing a game. It's an opportunity to make new friends and meet up with old ones. This was my third event, and each of them has been such an amazing experience. You and your team do a great job hosting. Thank you! Keep up the great work!

The Castle & Palace
“The setting was truly inspiring for the gameplay. Our GM was amazing, engaging, and uplifting. It may have been our group, but I can certainly see playing with all our party members in the future!”
- Scott
“It is an amazing venue. Big enough that you get to meet people from all over (my gaming table had people from 7 different states), but small enough that you don't get lost or feel overwhelmed.”
- Michael

Partnership with the H.P. Lovecraft Historical Society
We are proud to feature immersive gaming materials from the H.P. Lovecraft Historical Society (HPLHS), one of the most respected creators of Call of Cthulhu props and period artifacts worldwide. Their meticulously crafted prop collections bring scenarios to life with authentic documents, maps, letters, and handouts designed to feel as though they’ve stepped straight out of the 1920s.
At Cthulhu in a Castle, select tables will experience enhanced atmosphere using HPLHS materials, deepening the sense of mystery, investigation, and cosmic dread throughout the weekend.
We encourage all investigators to explore their incredible catalog of games, props, films, and Lovecraftian treasures at hplhs.org and their official store. If you love immersive horror storytelling, their creations belong in your collection.
