Insert compatible with Abyss®, and the Leviathan® and Kraken® expansions. The design provides both efficient storage and improved game play. Many of the trays can be utilised during the game, and they greatly aid set-up and clear-away times. The rules and boards act as a lid on top of the trays.

The trays are arranged in up to three layers. The location tiles are placed in a single stack at the top of the box, held in place by two filler trays.
