Plain tiles:

The so-called plain tile will be the most common type of them all, lacking any complex terrain features. Its purpose is to represent open ground, which usually imposes no penalties or modifiers to unit movement. It can also act as a base for any extra terrain pieces (like buildings) the players already have and want to include in their game. This Type will be covered in flocked Grass (temperate, Spring) and will be found in all Pedion Battlefield Sets. New designs were made available through Stretch Goals for all themes.
