Thank you for the clear and specific feedback! I agree the mine-to-town connections could be more explicit in the drawing, keying, or both. The dungeon does have a lot of loops doesn't it?
Rightly or wrongly, I intentionally put in a bunch of stuff for the GM to use that I don't have answers to. The Esoteric Order of Sanctified Knights, more idols represented on the box, worm tunnel fork and blocked mine exits. The traveling merchant was one of these things, intended to allow a Warden/GM to graft onto him whatever they needed him to be. As a character, I saw him as a kind of cross between The Dark Tower's Man in Black and Majora's Mask Happy Mask Salesman. But as always, no plan survives contact with the players and I could definitely see a party chasing his trail while bad things are left to happen in town. I wonder if Spawn can fly to the big city...
I'll revisit these things after the jam. Thanks again!
