sorry for m y bad english that s not my native langage.
A good, solid quest. I ve Dmed it in 4 hours with homebrew rules and very few fighting (and short) scene.
the zmek shrine is an interesting and short dungeon.
We did not have the time to play the dungeon the manor of kukovaitis.
the adventure is well - organized and avoid fighting gobelins
there are some interesting NPC and the adventure (short)is not rail-roaded : the adventurers can play a mercenaries party or the "good cops". (personnaly i make them play servitors of the new faith : they were particulary interesting in the secret cult of the old faith....)
all in all very good maybe better than other free Dnd adventure
