Griffons Forge now has their own website up and running. Get your terrain direct from the source.
From the announcement:
Griffons Forge is now open. All the great terrain originally sold under the Griffon Studio banner on Ebay will now be available at their own website, Griffonsforge.com. Most of Griffon’s Studio’s inventory is already available, including the Alien Hive line, and most of their Sci-Fi line. Over the next few weeks their entire catalog will become available. Updates for new products will follow afterwards and in the coming year.
