I've run this Adventure for 2 groups now, and, as a fairly green GM, I have to say I prefer it strongly to Ypsylon. The Characters are tighter and the pressure is more concrete.
5/5 stars, would transport eldritch horrors again.
Glad it was a a good experience, a1s! Ypsilon was a big inspiration. I tried to build on DG's work while making it as approachable as possible for new Wardens (i.e. me).
