They had almost been too late going through the gate.
As then went through, they all had sensed heat following behind them, and sensed a planet's death through the force.
It was yet another thing that they had become accustomed to because of the Vong.
Jacen and Tenel Ka were the first through the gate, and therefore the least effected by the shockwave that had followed them.
Jacen felt a mental communication from Tenel Ka, warning him that he wasn't alone, forcing him to think beyond his grief over Chewie.
It was something else the Vong had forced his siblings and friends to grow accustomed to-dealing with grief.
As he paid attention, Jacen noticed a group of approximately 20 people in an odd armor holding odd staff's, and a single person in a gold version of the armor.
"Um, hi" Jacen said, not knowing what to say "Jaffa! Kree!" Jacen had no clue what those words meant, but he received a clue when the soldiers began shooting at him and Tenel Ka.

As the Jaffa opened fire on the apparently unarmed group, Jack winced.
However, the two that were conscious grabbed small objects from their belts.
A green energy blade extended from the male's, and a turquoise blade for the redhead.
Much to the surprise of all of SG1, the two began catching the staff fire on their blades, and bouncing it back at the Jaffa, who fell dead.
As one of his guards was struck, Jack went into action, blasting another Jaffa in the face and tossing his staff to Teal'c as he dove after the staff of the Jaffa he had shot.
Several seconds later, it was all over except for the Gou'ald who was hidden behind his force field. Noticing the Gou'ald advancing on the sword people, Jack dashed for his hastily dumped pack and grabbed his throwing knife.
"Hey, snakehead" He shouted.
The Gou'ald turned, as expected, and raised his hand at Jack.
Jack struck first. His knife going through the forcefield and into the Gou'ald's hand.
Seeing the force field down, Tenel Ka struck. The Gou'ald fell to the ground in two pieces.

Teal'c's attention was riveted on the newcomers, despite their apparently being enemies of the Gou'ald.
"Howdy, you kids need some help getting back home?" Jack O'Neil asked.
Much to even Teal'c surprise, the boy began laughing, although Teal'c thought it was more of manic laughter, rather than anything from true amusement.
"Sorry, the last unconquered world in our galaxy sorta blew up behind us. Hence our rather explosive entrance." Teal'c noticed both young humans appeared to be very stressed.
"We are stranded here. This is a fact." Teal'c raised an eyebrow, her speech reminding him of a female cousin of his.
"Wait, another Galaxy?" Sam's curiosity had been piqued.
"That is a fact."
"How many symbols did you dial, seven or eight?"
"Eight, there was a coverstone on the chamber that ring thing was in that had eight symbols on it. Anakin," he pointed to an unconscious dark haired boy "noticed that only they matched the symbols on that dialing thingey"
"Sir" Sam turned to O'Neil "I believe that they are from another galaxy." O'Neil nodded.
"Conquered, you say?" Jack asked.
"The Yuuzhan Vong are from another galaxy. They massed their forces all around our galaxy's rim and began destroying worlds. They made no attempt at negotiation, and murdered any prisoners they took. They are a formidable enemy, and that is a fact."
"Umm, how did you find the stargate?" Asked Dr Jackson.
Both strangers looked confused.
"Stargate?"
"That ring thing" Jack gestured to the gate.
"There was an old legend on the planet Kashyyyk about a device capable of sending people to other planets instantly. Since were trapped on the planet, we decided our only hope was to look for it." The redhead's eyes blazed as if with a bad memory.
"How would a gate go undiscovered for so long?" Asked Sam.
"Kashyyyk's trees were many kilometers high, and the branches wove together forming a layered ecosystem with the treetops being the safest, and the ground being suicidally dangerous. Our ship was damaged when we landed, and our only option was to descend to the ground. Then we came across this old stone structure, and once we figured it out, we wound up here."
They heard a roar of engines in the distance.
"That alkesh is returning. We've got to get out of here. Everyone grab a body and head for the gate."
Jacen carried his sister, Jaina, after reactivating the droids; Daniel carried young Tahiri, Jack carried Anakin, Sam carried Zekk, and Tenel Ka and Teal'c carried Lowbacca.
"You are strong, despite missing an arm." Teal'c commented.
"I am a warrior."
"Indeed." Teal'c nodded his head with respect.
The gate swooshed to life, and Daniel fiddled with a small device strapped to his wrist.
"General Hammond, we've got wounded incoming. Some unknowns, friendly so far, ran into the Gou'ald as well." Jack spoke into a walkie talkie.
"Roger that SG1.Ill alert the guards in the gateroom." Jack put his radio back into its pouch.
"Okay kids, here's how it'll go. We've got guards all around the gate back home. Don't make any sudden moves, since we don't want to cause them to shoot you."
The two strangers nodded, and the robots didn't say anything.
