IMC the PCs are about to have a semi-real vision of the Sewn Sisters. The PCs will be split up and have to endure 3 trials (this was all lifted from the ToA Companion). I love the names of all 3 hags and might name drop them just to have some fun. The trials will have semi-real consequences too. In one, Baggy Nanna has the chance to rip off a PCs hand and a skeletal hand will replace it in the vision, but when they meet her in real life later on, she can control the hand like some Evil Dead 2 shenanigans.
I have to give it some thought to come up with good suggestions, but I had to say:
Man this sounds like a great campaign to be in!
