Dragon Forge Design is showing off their new 80mm Ancient Ruins base. Go get yourself some in their webshop.
From the post:
I added a new 80 mm Ancient Ruins with Round Lip base to the store today. Perfect for games with bigger models needing 80 mm bases.
Cast in grey urethane pressure cast resin in three pieces. Base and two pillar sections.
