Our Diceborn Heroes insert is composed of (8) trays and is designed to hold premium sleeved cards. There is a dice tray and three resource trays. The remaining trays allow you to store and organize the cards by their various sizes. The cards are meant to be sorted by their type rather than by their quest line. This shouldn't matter, however, since each quest line has an inventory card that instructs you which cards to pull from their respective type.
