This is a wall system developed specifically for FrostGrave and other skirmish games. It is designed to depict interior spaces Mine when it is advantageous to ignore flooring and external border walls because they are implied or quick set up is needed. The walls include a set with 6x2mm magnet slots . The room walls include 15 parts including: 1 4 inch block, 1 8 inch block, 1 corners, 1 T, 1 X, 3 walls with doors, end cap, 4 walls (both sets include 3 (x3), 4.5, 9 inch and mirror to use across from T and X sections.) Please keep in mind, as mentioned, this set is for quickly setting 3-8 fairly large interior dungeon rooms with scatter. All the componets are for situations involving small teams for squad combat. It is not for complex dungeon/mine crawls at all. We have dark age all wooden mine tracks if you need them.
