I'm just wrapping up a campaign of this after DMing it for around 30 4+ hour sessions. Overall I'd say that this is a really strong adventure, with a few issues that an experienced DM can iron out fairly easily. The biggest strength of the book is easily the incredible first opening in the little village of Vogler. Reading this chapter is what made me immediately want to run it. On top of that, this book presents a fantastic “linear” adventure. Most of the most popular and well-regarded 5e adventures (Curse of Strahd, Tomb of Annihilations, Rime of the Frost Maiden) are all fairly sandboxy, so this was a very welcome change. Just make sure you talk to the players during session 0 about exactly what kind of adventure there is and the kind of character they need to bring – nothing ruins fun more than feeling like you're on the rails for an adventure your character isn't invested in. The new mechanics are all fairly solid – the Kender race is fun, the Lunar Sorcerer is strong but not absurdly so, and it gives you a nice framework for giving people extra feats. As for downsides though… The later chapters really start to drag. Nothing is unplayable or terrible, but as-written the players will just be pointed at the next big thing they need to go see. After the first chapters handled the linear, cinematic story telling so well, this felt like a bit of a let down. Nothing was unfixable though, and it just took a bit of extra prep to make things a better fit for my group. In addition, I've heard other people more familiar with the setting complain that the dragonlance setting primer was a bit of a letdown. I found it to be more than enough for my purposes, but I didn't care all that much about having everything fit perfectly into the existing canon. If you love seeing how lore clicks together into a bigger world, then you'll definitely be left doing some wiki-diving to get the full picture. Overall, I think this is a good adventure for a new-ish DM that has run one of the starter sets and is looking for something meatier, but still easy to run.
