This is a tangential continuation of my previous Stargate-Frozen crossover. For those wondering, setting is the Milky Way galaxy following after the SG-1 movies (Ark of Truth and Continuum) but before Stargate: Universe and during the Atlantis expedition.

Gate to the Past

Chapter 1: Incoming Travelers

On some far off planet a great grey ring stood in the middle of a field of blue moss. A few meters in front of the ring sat a small pedestal, topped with an orange glowing orb surrounded by a multitude of rune engraved tiles. Despite the obviously artificial construction of these two artifacts, there seemed to be no other structure even remotely similar anywhere within view. The blue field in which the ring rested was completely abandoned, with no signs of life. The same could not be said for the forest that surrounded the clearing. Between the thick green branches, glimpses could be caught of all manner of strange and wondrous creatures, none of them visible for long enough to be identified.

Suddenly a panicked cry rang out from the depths of the forest, igniting a flurry of activity, obscured by the dense foliage. More cries emanated from within the shadowy woods, spreading through the forest in front of some unseen instigator. The cries of fear continued to spread through the forest, occasionally interrupted by a loud roar followed by an even louder explosion and then silence. Soon the calls had begun to die down as the remaining animals fled the vicinity of the strange new predators. With the calls subsided, silence once again returned to the small moss covered clearing, only to be once again be broken by the sound of snapping twigs and branches and the rustle of leaves. The shrubbery at the edge of the blue moss clearing parted, as if pushed by the wind, allowing a glimpse into the interior of the forest, and revealing a figure obscured by the shadows of the overhanging leaves.

The figure strode briskly into the clearing, allowing the sunlight to illuminate its form. Contrary to the usual inhabitants of this world the figure was humanoid, with two long legs emerging from beneath the large green overcoat that covered most of the figures upper body. On its head rested a massive green, wide brimmed hat, almost two feet across. The hat did well to keep the sun off of the strange figure, and obscured its face in almost total darkness, despite the bright light of the twin suns overhead. Another figure emerged from the clearing, another humanoid. Stepping into the light of the clearing, the figure showed itself to be a young woman in her late teens. She was clad in a black dress covered in bright pink flowers and wore a flower in her hair. A massive double barred gun was balanced on her right shoulder, thin wisps of smoke curling from one of its barrels.

Together the two figures crossed the blue field, both coming to a stop in front of the strange pedestal. The tall figure with the hat gently brushed back its cloak and withdrew a white gloved hand, using it to trace the shape of one of the runes on the top of the pedestal. After a while it moved its hand to one of the adjacent tiles and pressed it down, slowly and with great care, as if wary that too much force would break the ancient contraption. As the tile depressed a light appeared around its edges. Almost immediately afterwards, the large ring sprung to life with an electronic whir akin to a jet engine starting up. The circle inside the ring began to spin, only to stop again as one of the chevrons on the outside of the gate lit up.

"Unscheduled activation! Incoming Wormhole!" The sound of Walter's panicked voice added to the harsh symphony of hard rubber on concrete floors and the constant droning of the alarm. In the distance one could hear the regular sound of each chevron of the gate activating, the constant grinding of the spinning inner wheel growing louder until finally the electrical whoosh of the unstable vortex cut off the growing noise. Almost immediately dozens of metallic triangles moved in from the outside of the massive, grinding across one another to form a circular iris structure, converging in the center to completely block out the blue ripples that covered the inside of the ring.

General O'Neill rushed into the control room that oversaw the embarkation room below. He looked around quickly until he found Walter already busy closing the iris to prevent any intruders from invading through the open wormhole. After a few seconds Walter shook his head, his left hand raised to a set of headphones.
"No incoming signals sir." He reported before looking back at the various readings the gate was emitting "No abnormal activity either."
Suddenly a loud explosion emanated from the sealed iris, followed closely by another, and then another. The explosions continued for a few minutes at semi-regular intervals before the gate shut off again.

The figure continued pressing the tiles, its hand moving across the surface of the stone pedestal. The gate continued to spin, pausing as a new chevron was lit up, then continuing to spin. For each tile pressed one of the chevrons would light up with the same abrupt crescendo. Soon, all but one of the chevrons had been lit up, the topmost one remained dark as the figure that had been pressing the tiles rested its hand on one final tile. It turned its head to look at the young woman in the flower dress. The woman returned the figures gaze and nodded once before walking around to the side of the pedestal. With that the hat wearing figure pressed the last tile. The gate clicked one last time before falling silent.
"Now." The figure spoke, a surprisingly soft voice considering the rather stoic appearance it had.
The girl hefted the big gun off of her shoulder, allowing it to slap down into her left hand before bringing it up in line with her eyes. At the same time the figure pressed the orange sphere in the center of the pedestal.

With a whirling roar the gate engaged, a burst of wavelike energy streaming out from its center as the event horizon of the wormhole was formed. The burst soon retracted back into the portal, leaving behind a shimmering pool of standing water. As soon as the "water" had calmed down the girl with the gun began firing, sending loud explosions echoing across the field.

Shot after shot entered the circle of standing water. Four, five, six in total before the girl lowered her gun. She blew a bubble of chewing gum out of the corner of her mouth, allowing it to grow until it exploded with a small pop before turning to the tall figure.
"Think we made them piss themselves yet?" She asked, coyly.
"No." The figure responded, a hint of coldness seeping into its voice. "If anything we have ignited their curiosity."
"Sweet, that means they'll be dropping by so I can ignite every other part of them?" The girl asked, once again hefting the gun onto her shoulder.
"They will most likely send unmanned vehicles to investigate the source of the perceived "attack", but by then we will be long gone. We should however, leave a message, to let them know where they can find us."
The figure turned and proceeded to walk back towards the forest.
"Do make sure you leave the correct address, and once you have finished…" The figure paused to look over its shoulder at the six legged wolf like creatures that were now prowling the far side of the clearing, their lips pulled back to reveal rows of serrated teeth.
"… eliminate those beasts." With that the figure headed back into the forest, the shadows and foliage quickly obscuring its form.

A wide grin formed on the girl's lips as she turned around to look at the wolf-like creatures.
"Here doggie doggie." She taunted softly as she looked through the sights of her weapon.
Two sharp cracks echoed across the clearing, followed by brief silence as the alien creatures slumped to the ground.
"Easy peasy." The girl grinned as she walked over to a discarded stick and began to carve away bits of the mossy carpet, whistling as she worked.

O'Neill turned to Walter.
"Figure out what planet that came from and get a MALP ready." He ordered before turning to go back to his office. On his way through the base he ran over the attack in his mind, cycling though a list of possible enemies who could have known Earth's gate address. The Goa'uld were too scattered and distracted, the Ori were defeated and the few errant garrisons not under the control of a Prior weren't aware of Earth's address, although it was quite possible that they had discovered it. The Lucian Alliance was gaining power, but they had not gained the courage to attack Earth directly yet, but that still did not mean that an attack out of the question. Of course it could also be one of the countless other species they had pissed off in one way or another. O'Neill shook his head, sometimes he really wished Carter and Daniel were still around, they were a lot better at figuring some of this stuff out.

Back on that far away clearing the young girl tossed the now grubby stick aside, stepping back to admire her handiwork. Seven symbols, not unlike those depicted on the pedestal were now carved into the moss, revealing the black earth beneath it. A small square of parchment was laid carefully over the pedestal, on it were written five words.

Come and get us.
-UNIT

The girl rolled her eyes as she glanced back over at the note.
"Ugh, so cliche." She sighed "Why is Reb always so dramatic?"

I don't know if this will turn out as good as my previous crossover, so let me know if you think I should continue. If so, I will try to upload at least once a month.

For those of you wondering where the Frozen characters are, they are, well, frozen, somewhere else. I probably will not introduce them until the third or fourth chapter.

And remember, reviews are always welcome and appreciated.

EDIT: So apparently I went a little overboard with making the gun totting girl (not giving away the name yet) obnoxious. I'll tune her attitude down in the next chapters to make her more "sarcastic jerk" and less "punchable jerk".
