I've been wanting to get it back to the table lately, and found some of the latest supplement books on a great deal on amazon so I picked up:
-Frostgrave: The Wizard's Conclave
-Frostgrave GA: Gods of Fire
-Frostgrave GA: Cities of Bronze
I believe that gets me caught up with all the supplements for the two of them. What I'm gearing towards is being able to run through the scenarios in all the books in order. That should be a fun campaign to run. I've got pretty much all the terrain, and all the minis to do it in style. Now I just got to set aside the time.
