"Atlantis this is Sheppard we're on our way back" radios Sheppard "Glad to hear you're ok Colonel, did you find anything?" asks Woolsey "We found a crystal" says Sheppard "A crystal?" asks Woolsey "Yes, McKay's working on it" says Sheppard.

"Dr McKay will be very happy to know we have the flight controls back online" says Woolsey "That's great" says McKay "Hurry back Colonel we're ready to leave as soon as you're on board" says Woolsey "Leave?" says Sheppard "General O'Neill has ordered us to return to Earth" replies Woolsey "What's going on?" asks Sheppard "I wasn't told, I was just asked to return to..." says Woolsey but he stops talking "Woolsey?" says Sheppard "Colonel we have an intruder" replies Woolsey "Woolsey? Woolsey?" asks Sheppard but he gets no response.

On Atlantis a figure in black has appeared seemingly out of nowhere and is standing below the control room near the Stargate looking up and around at the people above.

A security team run through the doors on the gate level and point their guns at the figure in black but he doesn't seem to care "Don't move" a few of them shout "Stay where you are or I will order them to open fire" announces Woolsey and he heads for the staircase leading to the gate level and the figure turns and looks at Woolsey standing at the top of the stairs.

"Who are you" asks Woolsey but gets no reply "How did you get in here" asks Woolsey but still gets no reply "OK what is it you want?" asks Woolsey but still gets no reply.

Then they see a bright flash of light and appearing behind the figure is Chaya Sar, the Ancient, Athar. The security team look a little gob smacked and move back, the figure notices Woolsey looking behind him towards Chaya and turns around to face her.

Sheppard, Ronan, Teyla and McKay have made it back to Atlantis and are running to the control room.

Chaya and the figure look at each other for a moment "You are Alteran" says the figure "Yes, but what are you?" asks Chaya "I feel all life and all that exists in the universe but you...I do not feel you. Why?" she says sounding slightly puzzled.

Chaya walks up to the figure "What are you?" she asks and then without provocation the figure reaches out with his arm, grabs Chaya by the kneck and lifts her off the ground and oddly Chaya seems powerless to do anything.

Sheppard, Ronan, Teyla and McKay run into the control room and Sheppard looks at Woolsey "What's going on?" he asks and then he glances over and sees Chaya being held in the air by the figure "Chaya" says Sheppard under his breath and raises his gun and starts firing at the figures back "HEY!" shouts Sheppard continuing to fire.

Ronan joins in from the balcony above but despite their combined fire power it doesn't affect the figure so Sheppard attempts to tackle him but the figure pushes him away.

Ronan jumps from the balcony on to the figures back and starts 'pounding' him on the top of the head but the figure pulls him off by the face and throws Ronan against the wall. Chaya trying to remove his hand from around her kneck and choking asks the figure to stop "S..t..o..p" she says "Tell your people they can't hide from us" says the figure "Who are you" says Chaya struggling to breath and the figure brings her closer to his face and says in a menacing tone of voice ….."The Verdain."

The moment Chaya heard the name Verdain her eyes opened wide and her mouth opened with a gasp and the look on her face was one of absolute disbelief "No" says Chaya and the Verdain removed his grip on her causing her to fall to the floor and he faded away as quickly as he appeared.

Sheppard got to his feet and ran over to Chaya who is holding herself up by her arms and holding her head down and Sheppard kneels in front of her and holds her shoulders "Chaya" he says in a gentle voice and places one hand under her chin and gently lifts up her head to look at her. Chaya looks up at Sheppard and he can see she is very upset and has tears running down her face.

"It's ok he's gone" says Sheppard and Ronan walks over rubbing the back of his head "Ooaar..you ok?" he asks "Yeah, you" asks Sheppard "I'm good, is she ok" replies Ronan "Chaya he's gone he can't hurt you" says Sheppard to Chaya.

"We tried, we couldn't.." Chaya mutters while shaking her head and still crying "I have to go" says Chaya rubbing the tears away from her eyes she gets to her feet "Chaya, wait" says Sheppard but it's too late she vanished in a bright light.

Ronan and Sheppard start walking up the stairs to the control room "What was that thing?" asks Ronan "It called itself a Verdain or something" replies Sheppard "Col Sheppard, what just happened here?" asks Woolsey "Honestly I have no idea" replies Sheppard "Well if that thing is the reason we're being called to Earth then we better get there quickly" says Woolsey "Agreed" says Sheppard "Dr McKay take us in to hyperspace, we're going to Earth" orders Woolsey.
