In the pages of an ancient library visited by Sheppard’s team, McKay finds historical evidence of a zero point module. Historical documents on the planet Dagan indicate that the ZPM was kept as an object of worship and guarded by an order of monks, and they left a map to uncover the ZPM in several buried pieces. McKay and Sheppard’s team receive valuable assistance from the local population, though not all of them think they should be helping their new visitors so readily. Their combined efforts uncover an underground bunker, and Sheppard’s team goes to explore it with some of the locals, leaving Ford on guard. Another party on Dagan quickly makes its presence known: Kolya, the Genii commander whose forces Sheppard drove off of Atlantis during the storm. In the meantime, on Atlantis, a deep space sensor system is accidentally activated, and after a Wraith dart ship strafes the city, Dr. Weir orders a maximum-range sweep with those sensors – and discovers three massive Wraith hive ships are on a course for Atlantis.
