I was initially reluctant to read Scarred Lands material because it was published by White Wolf during the D & D 3.0 era.
With Nocturnal and Onyx Path on its own, that was no longer an impediment.
As for the adventure itself, the setting is moody, atmospheric dark fantasy. There is a lot of advice for integrating player characters into the setting and for modifying the adventure. The dungeon layout is unusual, a bonus, to me. The encounters are challenging, from what I read. I have one minor objection, a legacy era error from earlier editions of D & D. Instead of Challenge Rating, encounters are described by their Encounter Level.
