Campaign Seed Material

I admit it.  I'm working on a campaign setting.  A little bit between the other things I've got going.  I bought that Piccadilly notebook and jotting down idea, house rules as I think of them.  I'm setting aside some OSR created supplements to use in the creation of this campaign.  I'm trying to keep the list small because there is so much it could easily become overwhelming.  I specifically targeting things that are very specific.  Here's the list I have so far.

Kefitzat Haderech, Incunabulum of the Uncanny Gates and Portals by +Paolo Greco.  I wrote a review for it in May.  This book is going to be great for developing gates I have planned.  This is something I've never done in my previous campaigns.  Looking forward to adding this element.

Trick, Empty Room & Basic Trap Design by +Courtney Campbell.  And also by Courtney, Treasure.  He's a solid producer of gaming material.  I haven't used these before, but I've kept them in my campaign notebook for a reason.  I will definitely be referring to them this time around. 

I have a list of workshops, with guild deign sheets, but not sure where I got them from.  The list of shops is great for city creation. 

And the last thing I currently have is Medieval Mining by +John Stater.  It is from issue #5 of Nod.  One of these days I want to get all his issues.  John does an excellent job of breaking down what I want to do in game into mechanics or ideas I can use. 

This is the start I have so far.  I've decided to use the S&W Complete ruleset.  I'm looking for a few more cool classes to throw in. 

If you have any suggestions please let me know and add a link in the comments.  Thanks.
