 The team is exploring a planet with an agrarian society. McKay wants to leave as soon as possible. They have no interesting technology and barely enough food for themselves. Eldred, a village elder, has at first no time to speak with them. He was busy harvesting and preparing tribute for a Tower that offers the people protection from the Wraith. He is willing to show them it. It looks just the same as the central spire of Atlantis. Eldred tells the Tower uses bright lights to shoot down the Wraith, which the team recognizes immediately as the drones from the ancients. Although Eldred has never seen it used on the Wraith, he mentions a  Lord Protector  once in a while shows his power to the villagers by firing one of the balls. Sheppard asks Eldred to arrange a visit with the man.
