Lucian Alliance invasion of Destiny

"We've been informed that this ship faces an incursion from armed forces of the Lucian Alliance, the group responsible for the attack on Icarus Base. All military personel onboard have been placed on high alert. If the enemy has acquired the means to dial Destiny, their point of ingress will be the Stargate. So the gate room is off-limits. All surrounding corridors have been placed on lockdown. No one may enter without proper authorization. I've provided Homeworld Command with intel on the planet from which the Lucian Alliance intends to launch their assault. They're dispatching forces as I speak."

- Everett Young

The Lucian Alliance invasion of Destiny is an event that occurred in 2009 between Tau'ri and Lucian Alliance on board Destiny in an unknown galaxy.

Prelude
"He's about to try and make contact with the Lucian Alliance."

- Everett Young

As a result of switching with Col. David Telford using the long-range communication device, Dr. Nicholas Rush gained fragments of memory from Telford's mind indicating that he was a spy for the Lucian Alliance. Since Telford worked undercover in the Lucian Alliance for a year prior to his work at Icarus Base, it is assumed that the Alliance converted him using Goa'uld brainwashing technology. After consulting with Col. Everett Young, Rush decided to try and make contact with the Lucian Alliance members on Earth to expose and capture them. To do this, he switched with Telford during the next scheduled use of the device.

Young, not completely convinced that Rush was being honest, arranged for Rush to be followed covertly by Dr. Daniel Jackson, and in the meantime kept Telford occupied. Rush managed to make contact with the Lucian Alliance, but his lack of knowledge in their protocols revealed his duplicity and he was captured. Before Daniel could arrest the Alliance members, they escaped in a tel'tak.

Rush was tortured for his identity by Commander Kiva. Rush eventually broke and told her his name. Knowing who he is from Telford's reports, Kiva forces him to work on the Alliance's own research into dialing the ninth chevron, which had thus far been stalled due to their lack of the power regulation equation found by Eli Wallace.

Revealed as a traitor, Telford was interrogated on the whereabouts of Rush by Young, but Telford denied any wrongdoing. Young brought in Gen. Jack O'Neill to speak with him, since O'Neill had seen the effects of Goa'uld brainwashing before. Confronted by O'Neill, Telford admitted his role as a spy proudly. Seeing this, O'Neill authorized Young to use more drastic measures to break Telford. Young had the air vented from Telford's room, bringing him to the edge of death, then revived him, thus breaking the brainwashing. Telford warned Young of the impeding Lucian Alliance invasion and gave him the coordinates of the planet where their ninth chevron research was set up.

The George Hammond was dispatched to the Lucian Alliance outpost to stop the invasion. Unable to beam the occupants out due to jamming devices, she dispatched a squadron of F-302's for a ground assault. By this time Rush had made enough progress to dial Destiny at the cost of destroying the planet. Her hand forced by the attack, Kiva ordered the ninth chevron to be dialed and sent her men through, taking Rush with them. Col. Samantha Carter was forced to leave two of her 302's behind to escape the destruction of the planet. The F-302 pilots and over 100 of Kiva's men were killed in the ensuing explosion, but the rest get through the Stargate to Destiny safely.

Invasion
"You're all in danger. They're coming to take Destiny."

- David Telford

Travelling to Destiny severed the communication link, returning Telford and Rush to their original bodies. Kiva attempted to kill Telford, still believing him to be Rush, in retribution for the deaths of her people, but Telford convinced her that he wasn't Rush by using the code-word he used to identify himself that Rush didn't know. Telford also pretends to still be brainwashed. Having been informed of the attack, Young was prepared. The gate room was locked down and the atmosphere ready to be vented with the push of a button. However, the presence of Telford's body made him hesitate, and he instead decided to give them a chance to surrender. Young used the intercom to request their surrender, but his hesitation buys them the time they need to escape using specialized lockpicks to open the doors.

A firefight ensues between the two groups. The Alliance forces their way into the surrounding corridors, capturing ten Destiny crewmembers, among them Tamara Johansen, Hunter Riley, and Rivers. Four Alliance members are captured by the Destiny crew. Eli Wallace and Chloe Armstrong are forced to escape through an elevator, ending up near the bow of the ship where there's air but no active life support. Chloe also has a gunshot wound on her leg and is losing blood.

The two sides are at a stalemate. Kiva has hostages but Young still controls life support. In an attempt to trick Kiva, Telford leads a small group through one of the damaged sections to flank the Destiny crew, covertly informing them of his plan so they'll be lying in ambush and will be able get the drop on the Alliance. Before this plan can be realized, however, an intense burst of radiation vaporizes one of the Alliance soldiers, followed by a ship-wide power disruption. The plan is called off until the cause can be found. When Kiva learns of the soldier's death, she asks for medical supplies as a show of good faith to prove the Destiny crew didn't do it. Young attempts to use this opportunity to end the invasion, but the plan is foiled by another power failure.

It is discovered that Destiny has stopped within range of a binary pulsar which is emitting deadly bursts of radiation every 46 minutes. It is these bursts which are causing the ship to temporarily lose power, since Destiny is rerouting power to reinforce the shields. The FTL drive is also offline, preventing them from escaping. A plan is devised to reroute shield power from the side of the ship opposite the pulsar, but it needs to be done from outside the ship. Scott and Greer are chosen to do the work.

The fastest way to the shield emitter on the hull is through a breach in Kiva's section. She leverages this for control of the ship. Telford convinces Young to go along with her request until he can transfer control back to Rush and Brody, who take refuge in another control room. However, his plan goes awry when he is caught in the act by Kiva and they both shoot each other. Kiva is unconscious but alive; Telford's fate is not revealed.

Assuming Young's people to be responsible, Dannic rounds up the military to execute them, leaving Scott and Greer trapped outside. Rush reroutes them to another section of the ship near Eli's location, so Eli can let them in. In the infirmary, one of the Marines attempts to overpower an Alliance soldier. The soldier's gun goes off in the struggle, hitting T.J. in the stomach.
