Update: You can now buy The World Beyond's Samaris Game Companion in full color print (also inside) from DriveThru. It's a full city setting for more narrative role playing, with over a hundred contacts, as many locations, creatures, adventure ideas and artifacts. It was written for The World Beyond RPG, but you could use it with minimal tweaking in any favorite fantasy game system, be it O5R or something else.
The black and white version (older Dark Dungeon rules) is no longer available. That is, unless you want one of the few remaining ones I have left. Leave a message if you're interested. The Samaris color print and pdf is right here.
Have a look at the positive reviews of the first (B&W) edition of Samaris here. The new version is even better.
Here is a picture of that first edition's b&w print. I had some issues with the printer at first, with big black spots appearing instead of transparency. I was so proud when I finally got it right :-)
