This looks really good, it's laid out very well, it has some pretty crunchy mechanics that give the GM a very clear idea of how to run the adventure, all stuff that I love to see. The only things reading through that jump out to me are bits that get a bit brushed over, like at the beginning the party follows the embers for a three hour journey...does anything happen on this journey or do we just fast forward to the end? It might be interesting to add some random encounters or other obstacles that create memorable scenes, or if you just want to fast forward to the adventure that's okay too but the way it's written suggest that maybe the GM should try to stretch that phase out a bit.
Really great job!
