A Sarcophagus (or Sarcophagi) were a type of coffin used by the Ancient Egyptians. The stylised technology of the Osirian lodestone had the appearance of an ancient egyptian coffin of the Pharoah. There were also others that stored the Osirian's service robots, who appeared as mummies. (DW: The Pyramid of Mars)
