Cult actual-play D&D show Legends of Avantaris have created The Crooked Moon, a 600+ page folk-horror setting for 5e Dungeons & Dragons 2024 (and 2014).  

The game swaps out the usual setting for something more Summerisle-inspired,  with 15 new subclasses, 13 lineages, and new spells, rituals, and items. There are also folklore-inspired story hooks to get your adventuring party together. They’ve crammed a load of monsters and the full Wickermoor Hollow campaign in as well.

Legends of Avantaris are perhaps best known for their ‘horror-themed’ D&D YouTube shorts, including Chuckles The Clown.  The crowdfunding campaign to produce The Crooked Moon raised over four million US dollars.

Pre-orders can be found here, and the full release is coming to DND Beyond on June 16, 2025.
