It's been a few hours since Chaya and Lya left Atlantis to try and convince the other Ancients to join the fight against the Verdain, and now that everyone has learned who the Novum and Verdain really are, they seem calmer and much more trusting of the Novum on board.

The Novum, along with Woolsey, O'Neill, Daniel and Carter are back sitting in the briefing room.

"How many Verdain ships are we talking about?" ask O'Neill, looking over at the Novum and rolling a pen between the thumbs and fingers of both hands.

"I don't know exactly, may be 6-7 hundred." replies Raina.

"And they're all like the one you stole?" asks O'Neill.

"Yes. We saw a really big one though before we came through the energy field, it was almost as wide as the field itself." replies Jomar.

"At least 50 times wider than the little ships." adds Raina.

O'Neill turns and looks at Woolsey who share a worried expression, Woolsey looks down at his tablet computer which he's been using to make notes of all the previous briefings.

"How big is the Verdain army?" asks Woolsey.

"There's about 7000 of them now." replies Raina in a saddened tone of voice.

"I see." replies Woolsey compassionately, then he lowers his head a little.

Daniel takes in a breath and looks across at O'Neill and then the Novum as he leans forward in his seat.

"So...you have no idea how the Verdain did any of this?" asks Daniel.

"No. All we know is they left Sehabo after they committed their terrible acts against our people, we didn't see or hear from them again until a few years after that." replies Raina.

"They must have been planning it for all that time, and there's no way they could have built all those ships after we were taken to Intrius. They were built long before we arrived." adds Alisana.

"Raina, you also said you saw them transforming the Novum into...orange energy?" questions Daniel.

"Yes. They went into a chamber and were turned into some type of energy, then the energy went into a suit of armour." replies Raina.

"So the energy controls the suit. Could it be living energy, like an Ancient, like Chaya?" asks Daniel.

"I'm not sure." replies Raina.

"When we overpowered the patrol and removed their armour, the energy was gone." adds Jomar.

"OK I know you said we can't kill these things, but if we remove their armour, that's it, they're gone...right?" asks O'Neill.

"I'm sorry we just don't know." replies Raina.

The room falls silent again for a moment, then Carter twirls to the side in her chair, gets up and starts walking towards the end of the table.

"Can you tell us anything about these?" asks Carter as she picks up a metal box from the table then walks over to the Novum and places it in front of them.

Carter opens the box revealing the two crystals cushioned snugly inside by protective foam, she turns the box around by the lid so the Novum can see them.

Raina reaches in a pulls out one of the crystals and has a good look, "I've never seen these." she says, Raina shows the crystal to Jomar who has also never seen them before.

"OK, it was worth a shot." says Carter.

"I know what this is." says Alisana as she gently takes the crystal from Raina's hand.

"You do?" asks Carter, with interest.

"This is a Nuntus." replies Alisana.

"A Nuntus." says Raina, sounding quite excited.

"OK, what's a Nuntus?" asks Carter.

Alisana shuffles her seat forward and closer to Carter, who is leaning over the table.

"The alliance of races had a council, a member from each race chosen to represent their people. Each member of the council was given a Nuntus, it's used for lots of things, accessing the council chambers, allocating resources to various worlds and casting votes on what is best for our people." explains Alisana.

"A government?" asks Woolsey.

"Yes. Like our colony on Sehabo, the council members had to vote on whether it should go ahead or not." replies Alisana.

Carter bits the side of her lip and has a slightly disappointed look on her face.

"Is something wrong?" asks Jomar.

"No, no. Well I was just hoping it would be something more than that." replies Carter.

"Oh but it is." replies Alisana, with a smile on her face.

Alisana looks excited and get up from her seat and makes her way around the table to Carter, she holds out the crystal in front of her.

"With this, we can access the Yaculum." says Alisana.

"No way. The Yaculum." says Raina, who also gets excited.

"What's the Yaculum?" shouts O'Neill from the back of the room.

"The archive, it's where our people stored all of our research, knowledge and prototype technology. Pretty much everything that was created and shared by the alliance is stored there." replies Alisana.

O'Neill, Woolsey, Daniel and Carter look at each other for a moment, then O'Neill, Woolsey and Daniel get out of their seat and walk over to Carter and the Novum.

"Technology you say?." asks O'Neill

"Yes." replies Alisana.

Now everyone is excited and smiling at each other.

"You wouldn't by any chance know where the...Yaculum..is..would you?" asks Carter, cautiously.

"Are you kidding, I've been trying to get in to that place since I could walk." replies Alisana.

"So that's a yes then?" asks O'Neill.

"Yes. I know exactly where it is." replies Alisana.

"Oh, McKaaaaaay" shouts Carter as she leaves the briefing room followed closely behind by the others.

Zelenka and McKay have been trying to figure out what's happening to Medrona, but haven't had much luck and the planet is now only just visible to the eye. McKay is sat at a console typing on his laptop when Carter rushes over and pats him on the shoulder.

"Hey, McKay. I found out what one of the crystals is for." says Carter.

"Oh yeah, good for you." says McKay who didn't even look at Carter and just continues typing on his laptop.

"Don't you want to know what it's for?" asks Carter.

"What?" asks McKay in a low and uncaring tone of voice.

"Oh nothing really, it's just a key to possibly all the Ancients technology." replies Carter.

"That's great." says McKay, again in a low and uncaring tone of voice.

Carter smiles and walks off, then McKay realises what she just said and springs to his feet.

"What did you say?" shouts McKay.

"Nothing." replies Carter.

McKay walks over to Carter with a childish smile and waving his finger.

"No, no, no, no, no, no. You said Ancient technology. Does that contain information on Ancient technology?. Because if it does then I should probably take a look at that." asks McKay, while pointing at the crystal.

"Not information, McKay. Actual technology, and not just the Ancients technology but the Nox and the Furlings too." replies Carter.

"Are you serious." replies McKay with a stunned fish like expression on his fish.

"Alright, Alisana where is this..Yack..thing?" asks O'Neill.

"The Yaculum is on a planet called Lemea."

Carter hears O'Neill ask Alisana where it is, so Carter walks over to them and points to the gate console.

"Do you know the gate address?" asks Carter.

"There's no Stargate on Lemea." replies Alisana.

"Here, you can show us on this." says Carter as she moves across to the navigation console.

Carter brings up a map of all the planets in the Milky Way on the display.

"OK this is where we are now, this is Earth." explains Carter while pointing our locations on the display.

"There." says Alisana as she points out a planet to Carter on the display.

"There, are you sure?" asks Carter.

"Yes, that's Lemea." replies Alisana.

"What is it Carter?" asks O'Neill.

Carter stands up straight and faces O'Neill. "Sir, that's P3X-562, the planet with the crystalline entities." explains Carter.

"Help me out here Carter." says O'Neill who looks puzzled.

"It's the planet with the blue crystals, the ones that took your place when it thought it injured you, and it took the form of your son sir." replies Carter, delicately.

"Ah." replies O'Neill.

Carter turns back to Alisana who originally said the planet had no Stargate "Alisana, this planet does have a Stargate. Are you sure this is the one?" says Carter.

"Possitive. It didn't have a Stargate the last time I was there." replies Alisana.

"Well let's not forget you've been gone for a long time, they could have put a gate there sometime after." says Daniel as he steps in to the conversation.

Suddenly a beeping alarm goes off on McKay's laptop and he rushes over to it.

"Oh no." says McKay.

"What is it?" asks Carter.

"Medronas gone." replies McKay.

Everyone rushes over to the external display that was showing Medrona, when they get there they see what just looks like a plume of space dust where Medrona use to be. A sense of loss fills Atlantis and even though they knew they could do nothing about it, they also know they have to work fast if they want to stop this from happening to any other world.
