First pros:
Journey rules, conseil rules and shadow rules. It will be easy to jump full rules after these!
So all in all good starting packet!
And then some critics:
It would be good if there would be short description of the small area around the Bree in the packet with some suggestions to further adventures to the completely new Lore master! Similar like Shire supplement in Shire starter set. Yes, there is more info in full rules and Ruins of the lost Realms and Tales from lone lands, but something to start before jumping to deep end of the pool!
The adventure:
I expect a lot of full party vipe outs when all adventures die. Not a good, not a bad thing, just how this adventure works out. Maybe it would have been nice if there would have been small preliminary adventure. For example group would be caravan guards from Blue mountain to Bree and meet small combat against small group of bandits in the way. Then arrive (hopefully to Bree) and make a counsel adventure to convince Bree-landers to hunt down the rest of the bandits. If they fail they would meet Gilraen who would encourage players take care of the problem themselves and if they succeed Gilraen would be impressed and give this adventure where they will definitely die

Aka first meeting with a Patron! That would help Loremaster to play out Patron meetings in the future and also allow small adventure where group would maybe win in some part!
And now the adventure:
part 1:
- It would have been better if there would have been more flesh out journey events. What happens if they get shortcut or Change meeting or Joyfull sight event to give more examples to new Loremaster! Fleshed out scenes tailored to the environment where adventure does happens. The rule suplement does not give a lot of help in this to new Loremaster.
part 2:
- The company may fail even at this part. What happens if part of the group die at this part? Examples how to continue to Loremaster when half of the party die in the fist combat! Aka tips how to proseed when things goes south.
- There is no info how Loremaster would proceed if the party fails the council part! It is very possible that they get zero information out of the children's! So more examples and options to new Lore master. How to help party again to right direction even after they don´t get the tips that children would have give. Maybe some example in rulebook how council can go. Also some examples of journey events in the rule supplement would be nice. This is a guide to completely new Loremasters after all!
part 3:
- This is the most flesh out part of the adventure. I just is most likely that party die or lose badly. Some tips to new Loremaster how to handle that situation!
All in all good stuff, but new Loremaster most likely need more support to many situations that may arise!
