This hex board (6 per side/91 spaces) can be used for Cyvasse, and comes in 4 parts (3 sections and a centrepiece) that fit together. It is suitable for my standard size pieces which have a base that fits into the holes and keeps them upright. The holes in between hexes allow the fortress piece (in the Cyvasse piece set) to sit on top of the desired space. The model is coloured, so is available in full colour sandstone only.
