Genii invasion of Atlantis

"This is the rarest of opportunities. Within the next hour there will be less than ten people on Atlantis, most of them only scientists. Now surely you can accomplish our goals and get out before the storm hits."

- Cowen

Genii invasion of Atlantis was an event occured during Lantean storm in 2004 during first year of expedition operations.

Prelude
"You don't want to make an enemy of the Genii"

- Cowen

First contact with Genii - race of humans posing as simple farmers, who secretly developed relatively advanced technology, led them to make an alliance with Atlantis expedition. However, their first joint mission ended with conflict between them. Atlantis Expedition took Wraith data storage device away from Genii. Meanwhile, Genii was impressed by Tau'ri technology, especially C-4 and desired to acquire some for their atomic bombs.

After discovery of Lantean storm heading straight to Atlantis, Rodney McKay wasn't sure city will manage to survive it without shield or submersion ability. Therefore Elizabeth Weir decided to evacuate all expedition members except several key person, while McKay and Radek Zelenka was trying to use lightnings as power source to the shield. This information leaked from Manarians to Genii who saw perfect opportunity to raid city.

Attack
"As of right now, we are in control of Atlantis."

- Acastus Kolya

Using IDC acquired from from athosian Doran and posing as wounded athosians, Kolya's strikeforce passed stargate shield of Atlantis, killed two guards, captured Stargate Operations room and held Elizabeth Weir and Rodney McKay hostage. At this moment John Sheppard was on the far end of the city operating grounding station and Teyla Emmagan, Aiden Ford and Carson Beckett trapped on the mainland unable to take a liftoff due to storm.

Kolya demand Wraith data storage device and all of the medicine and C-4 expedition possess. McKay managed to broadcast this demands to John Sheppard. Kolya acquired one of the Tau'ri radios and talked to John, who claimed he hid C-4 so Genii will never find it. He demand to release hostages and let expedition to leave city in excange for explosives, but Kolya already realized that city could be saved and he may not only capture valuable resources but city itself.

John Sheppard was cought in final grounding station. Unfortunately, skirmish between John and Genii caused damage of the station. Kolya in his turn claimed that he is going to kill dr Weir.

Kolya claimed that he killed Weir, but he actually didn't being persuaded in their importance. Meanwhile, John got advantage in his actions by ancient life signs detector and his knowledge of the city, allowing him to get Genii soldiers by surprise. Beckett's jumper finally was able to liftoff because the eye of the storm approached, so they head to Atlantis to help John.

John started to sabotage power generators. Without city-wide lifesign detectors Genii called for reinforcement to retake and guard generators. Ford, Carson and Teyla successfully returned to Atlantis. Meanwhile reinforcements arrived, unfortunately, Sheppard got into Stargate Operations and activated the gate shield, killing 55 of 60 people.

Kolya finally revealed to John that Weir and McKay are still alive. He once again treats to kill them if he won't return vital components of naquadah generators. Near one of generators John was ambushed. However, Ford's group appeared and rescued him. In the same time Sora arrived near generator room.

McKay finally repaired damaged grounding station and all of them returned back into control room. Against Kolya's order, Sora followed Teyla looking for revenge for her father. They were engaged in knife combat, Sora was overpowered.

Genii retreat
McKay was unable to activate the shield and Weir persuaded Kolya to abandon city. They were trying to take McKay and Weir with them, but was stopped by Sheppard and Ford. Being shot, Kolya fell into event horizon.

Everybody who left in the city, gathered in the control room. Rodney finally managed to activate shield saving city from drawing.

Aftermath
City survived storm, albeit took damages a Atlantis expedition returned home. Left behind, Sora is now prisoner of expedition.

Kolya survived and now he considers John Sheppard his own sworn enemy.
