This module is very well integrated with the City of Stangers guide to Kaer Maga. Both books were written by Paizo staffers so that might have helped the in-house coordination. There are lots of references to the people, places and history of Kaer Maga (complete with page references for quick look-ups).
You might think this module is only a low level dungeon crawl, but there are many seeds for future sandbox adventuring in and under the city of Kaer Maga. There are little hints for storylines that GM's might want to develop in the future. Great ideas are included without providing too much info. Take the thread idea and develop it for your group in the future.
Bottom line: Buy this module along with City of Stangers and you will have a great intro adventure and city setting to start a city/dungeon campaign.
The Pendragon books by Green Knight Publishing are on sale here at Paizo for $1 each.
This book serves as a great source book - listing important people and places with a brief description. If you are not that familiar with Arthurian legend this is nice to have by your side as you read other Arthurian books.
I recommend you pick this up along with several other books in the line. Hey, they are only $1 each - grab the whole line for $13!
