This is a well-written mod. At first reading of the, I was able to envision everything in my head easily.
The best thing about this adventure is the emotion; it allows for a lot of RP (from the DM, at least). I think it is a great mix of combat and RP, and fast-paced as well.
I like the wild-card in the tree; she allows for an easy way to help out a struggling party.
I'm not familiar with the season 1 story, I picked this out as a one-off for my group, so I wasn't as connected or familiar with the NPCs, but I still was gut-punched by the fate of one of them. It made me want to run more of the season.
