Sarah flops down into a chair, deciding that sitting was probably more likely to keep her from stalking out of the tent than remaining on her feet.
"OK," she begins slowly. "I'll own up to the briefing us lowly nurses got was woefully inadequate, but there has got to be a whole lot more to this than some ancient doodles."
"Bear with me, since I haven't really be trained in any of this and feel free to correct me when I've got some of the details wrong, since this is just about as far from my cup of tea as you could get...but here is where I am coming from"
"Long ago in a galaxy far away there lived a race we now call the "Ancients." There was a big civil war with the Ori and they packed up and wound up settling on Earth. About 50,000 - about when we believe that humans evolved from chimps - a plague decimated the Ancients living on Earth and they hopped aboard their spaceship Atlantis and jetted on over to the Pegasus Galaxy where they lived happily for many millennia before having to flee the Wraith and gating back to Earth. Among that group were the likes of Merlin, Morgan, Arthur, and a host of other personalities that we think of in the tales of Camelot and of the round table."
"So," she continues, carefully calculating her argument, "we had a nice little Ancient enclave up on the British Isles. Anyone surprised by the number of people with the ATA gene who can trace their lineage back to the Isles? Would it shock anyone to know that the ATA project has found some very curious relationships among those who they have identified with the ATA gene?" Sarah shakes her head, realizing she has drifted off topic.
"Point is that about 2000 years ago, if we trust these legends, some rather prominent Ancients were living among the primitive residents of the Isles. What they were doing is anyone's guess... except we are starting to have a guess that it had to do with controlling time."
"Now, there is this star thing... Why is it a 5 pointed star and not a 6, 8, or 10 pointed figure - its not like we don't have the glyphs for it," she says gesturing to the sketch of the dialer. "Obviously there is something about the order of the pentagon and star, as well as the number of vertices. Dr. von Braun suggested that this figure is seen in many cultures, including on Gawain's shield. My only real familiarity with these pentagrams is all the Hollywood-demon-worshiping-horror-movie-hype. Not that I buy into demon summoning, but there is always a skein of truth in fiction and I'm really hoping that someone can assure me that this pentacle has meant more to other cultures than demon summoning before we go and start dialing and having things from the ninth circle of hell greet us. I draw the line at venomous hexapeds."
