Beware the Greye Cliff Fortress!

W. Navarre ended the year with a flurry of activity aimed at the 13th Colossal Castle Contest and might have a shot at the Master Builder prize with the breadth and variety of his entries. My personal favorite is one of his last, this foreboding fortress built into a cliff that appears to be spewing lava!

In addition to the fearsome skull on the front, the fortress has an interior. Behind the door is a working portcullis.
