The Shadow Stacks functioned as the underground division of the Graf Archive located on Orchis 2. Unidentified artifacts were kept in this location while they were awaiting assessment. A collection of maps, crafted by hand from the Ithorian artist named Gammit Chond, remained in the Stacks for a multitude of years before an archivist student discovered them. In a separate incident, a different student was assaulted by a ghest within the Shadow Stacks, because the student did not recognize that the ghest was in a state of hibernation.
