I ran this for an online convention over the weekend. We ended up finishing in about 3 1/2 hours (I imagine it would be closer if the players rp'd more or did gamble at the beginning, my players didn't gamble). We had 5 out of 6 pregens in use-Tallulah was not used.

I would suggest with the Geology and Astronomy rolls that is called for, to give those skills to Johnny, Clay and Tallulah. If I remember correctly, one of the set-up paragraphs in the beginning, Finnegan also gets to do a geology roll if presented with the rock by the prospector, so maybe give him some geology skill even if it's the worst of who has the skill. I would also give Johnny and Tallulah some points in Occult. I wouldn't change Hugh or Clara too much.

Overall we had a good time with this scenario, and I will likely run it again with the character tweaks listed above.

Nice short adventure. I am buying up pretty much everthing that I can use for Down Darker Trails and Yig's Teeth is well worth the price. Has some nicely fleshed out pre-gen characters as well. Worth a gander.
