Vessels are objects which are infused with Sekhem as part of the ancient magic of Irem. According to the Arisen, vessels are instruments of the Judges' will, lesser than the mummies but still a part of the pattern of Fate. There are two types of vessels: vestiges and relics. Vestiges are repositories of unrefined Sekhem which hold memories of those that created them. Mummies use vestiges to recapture their forgotten memories and reestablish themselves (in game terms, mummies who encounter clues to their past get experience points that can be spent on increasing their Memory ratings).
