I GMed this at high tier and thought it went very smoothly, with good information and descriptions provided. The players also enjoyed it immensely.
This has a good mix of adventuring encounters away from the comforts of a city. The players are in a wilderness and that presents challenges. Some of those are potentially at the tougher end of the spectrum, but nothing here goes beyond a real sense of danger and challenge.
Looking forward to running this again this weekend!
