The Hess Drive was a [[ZZ-level]] artifact in [[Kester City]]. It was recorded destroyed in the Delijn Reactor Meltdown. All information about its purpose and correct operation was lost in the [[Second Destruction of the Golgari Library]]. Between the two disasters, information is sketchy. Our primary sources of information are Golgori historical records (always unreliable), and a single still frame of a schoolchild watching an educational program showing the Drive, found in an [[Atemporal Anomaly]]. Archeologists identify the markings on the object as first-millinium Kilt'iir (see [[Kilt'iir, the]]). Study of the Hess Drive is believed to have led to Temporeactor technology (see [[Delijn Reactor Meltdown, the]], [[Incandescent Temporeactor]]), the temporal warp engine, the discovery of [[Universe-Universe Binary Interaction]], the revised quantum-loop theory of [[Psychic Attunement]], and the theory of progressive ergonomic adaption. Study of the Hess Drive caused the [[Vvvelll Auto-genocide]] (see, [[Sanity Certification]]). Rarely have so many civilizations been so profoundly impacted by single object. The previous existence of the Drive was re-discovered by Joseph S. Hess II in RODS 56580a during routine digital archeology in the [[Kester City]] pseudo-anamoly. *Historical Plaque in the Joseph S.
