OOC: Anyone can get involved in this topic, though I'd prefer to keep it down to two others once those get involved. The system, I want to be uninhabited, but something like another scout ship, etc.
IC:
The Tenksileb exited the bowels of hyperspace with a small fleet of ships. Brigadier Makar, the commander of the fleet, immediately ordered, "All stop. Preliminary scans of the system?"
"Sir, we've completed preliminary scans. There are eight planets. Two class M, three class Rs, two J-class, and a single Terran class planetoid."
"Order the fleet to deploy across the system. I want detailed scans of the entire system as soon as possible."
"Yes, Brigadier."
"And I want the Tenksileb to take point at the Terran class planet. Order terrestrial labs to prepare for a detailed geographic study of the planet."
"Yes, sir."
The Brigadier stood from his command chair, and stated "I'll be in the Control Room."
He walked quickly and surely out of the bridge and down a stairwell into the interior of the ship, where he arrived at the Control Room. The Sergeant-on-duty immediately stood, saying "Brigadier, sir!"
"As you were, Sergeant. Have you derived this system's Astriaporta address."
"Yes, sir."
"Well?"
After the sergeant gave him the address, the Brigadier ordered: "Excellent. We need to communicate to S'net as soon as possible. Commence dialing."
"Yes, sir." The sergeant reached to a microphone that spoke into the Embarkation Room: "All hands, evacuate the Embarkation Room!"
The sergeant began quickly typing on his computer as the Astriaporta began to glow, and it's inner disk, covered with constellations, began to rotate.
"Chevron one, encoded." stated the voice of the Sergeant as the first chevron glowed with decision, as the sergeant continued: "Chevron two, encoded. Chevron three, encoded. Chevron four, encoded. Chevron five, encoded." The Astriaporta rotated halfway around as the Sergeant said "Chevron six, encoded," and there was a moment of suspense as the last symbol rotated into place....
"Chevron seven....LOCKED."
The seventh chevron locked into place, sealing the Astriaporta, as a brilliant splash of water came out of the ring, which immediately retreated back into the ring as a vertical puddle of water formed, the event horizon of the wormhole.
"Transmitting GDO code, sir..."
OOC: You can break in here. This is identical to any other wormhole, except it's controlled and for personnel movement, so anyone could detect it if they could detect a standard wormhole.
Oh, and for reference to the Astriaporta, it is for most intents and purposes identical to the device described on Wikipedia, under "Stargate (device)". Just technical, though. Historical information is all changed.
