i really like the point crawl within a hex. having a hazard per trail and an encounter per point really packs a lot of content into a little space.
figuring out what happened to ser koschel is a fun premise, but i could see it falling flat without the dowager's involvement. to that end, the other two hooks seem superfluous. the dowager is the juice.
gonna keep this one in my back pocket for my ongoing dolmenwood campaign!
