This Campaign 3 insert is designed to be compatible with Terra Mystica®, and the Fire and Ice® expansion. The design provides both efficient storage and improved game play. The trays can be utilised during the game, and they greatly aid set-up and clear-away times. The insert is arranged in three layers. There is one for each of the nine factions, and they have a divider to separate the larger buildings from the smaller pieces.The favor tiles are arranged with a separate slot for each of the four cults to aid game play. The terrain tiles are stored vertically and at an angle so they can be quickly sorted through to find the needed type. The boards and rules go on top of the trays acting as a lid, allowing the game to be stored vertically. First goes the game rules. This is followed by the main game board, and the faction boards and the cult board. Lastly go the turn order board and the cloth bag. The insert is designed to hold 4 faction boards and the cult board. Adding a fifth faction board will cause the box lid to lift by 2 mm. This allows the game to be packed ready for a game away from home, and carried safely and organised. The remaining faction boards and the game board variant, together with the rules in languages not needed, should be stored in the Fire and Ice box. This product consists of a flat-pack of 6 Evacore sheets. The trays require assembly, which is quick and fun, using ordinary PVA glue. Detailed instructions are included in the package.
