An installation art piece designed and constructed by West German artist Sebastian Keiner, who displayed it, for a time, at the De Young. It operates as a means of traveling, temporarily, from History A to History B. Keiner said that he used it to commune with the angels who were his inspiration, and to send young women to his masters in History B. Jocasta Menos entered it and was subject to intense psychic bombardment. Mitch Hort sabotaged it with his pyrokinesis, after which Marshall Redgrave arranged for its transportation to Livermore for containment and study.
