From the campaign:
RAVENFELL features our exclusive FOLD-FLAT terrain system which allows you to create fully modular 28mm scale village buildings for your RPG or wargame. The buildings are comprised of separate, stackable components, which can be mixed and matched between models for even greater variety, and folded flat for easy storage. Each village set is delivered in a downloadable PDF format via our online distribution partner DriveThruRPG.com, and once you have the set you can print and build as many pieces as you like and never run out or need to purchase more. Additionally, our graphic layer options allow you to customize your building to suit your tastes. This new village set is the culmination of nine years of terrain design experience, combining the best features of our previous sets such as modular components to mix and match, 2D interior tiles (now removable and swappable for maximum versatility) and fold-flat major components, creating the ultimate fantasy village terrain series! All sets include a 1" grid and grid less texture options.
