There are four trays for storing large cards, two vertically at the side of the box, and two for horizontal storage of cards . There is one more card tray for the small cards. The cities and towns go in one long tray, and the explorers in a separate smaller tray. The second long tray is for the blight, fear markers and the dahan pieces. The other two trays are for the player pieces and the beasts, wilds, disease, and strife tokens form the expansion. This game boards need to be placed in the box in the following sequence. First go the spirit panels on top of the lowest layer of trays on the left. This is followed by the adversary and scenario panel cards, and then the invader board. The invader board extension goes next. Then the expansion rules followed by the island boards, and lastly the game rulebook goes on top. This product consists of a flat-pack of 4 Evacore sheets.
