It was supposed to be a low-risk mission just dipping their toes back in the water. And of course it's not. There's wraith there and they have to run. The manage to dial fine, they even manage to get to the gate but as they're jumping through several wraith shots hit the gate and something goes strange. The normally smooth passage of the wormhole twists alarmingly and it's normal teal green shifts to a much more menacing red. And when they're finally spat out. They certainly aren't back at Atlantis.
"The stories vary, they're usually antagonists but they aren't usually inclined to destroy everything. In one of the more famous stories they're depicted as having a kingdom."
"I wonder why. Maybe the others don't match as well as you're thinking they do? Probably not, though."
"There are a lot of stories. It's possible we just haven't heard the right ones to match the Greenskins. Also... the way the translation system seems to work is by picking the most similar words if they exist."
"You know, I spent about half a second worrying about why you look foreign but speak Kislevarin fluently, right at the start, but it wasn't Dark Tongue so it was a future problem and the lady witch didn't take issue so I dropped it. It has a usual way it works?"
"We don't entirely understand it, but the gateways we travel through teach us the languages of our destinations. We've studied it a bunch so we understand a lot of what the effects are, we don't have nearly as much understanding of how it does it."
"The effect is something the gateways do while people are passing through them, it can fade after several more trips to places with different languages but it doesn't fade with time, there was a three years study with some volunteers. There isn't any mechanism for it to be contagious."
"Well, hopefully when you get back you now know the other half of the gateway isn't needed, and then never have to use that knowledge again." He'll let Teisa know but it doesn't sound all that worrying, they were already going to limit exposure to what these people said in case of weird Tzeentch bullshit.
"That makes it more of a mystery since we thought it was using the other end to get the information."
"...Okay, that's a bit worrying. We should... probably monitor all four of you for signs of insanity the way I suggested for if and when you look at the portal data."
"Honestly that's understandable. I don't feel any different but mind effecting stuff can be subtle. It always makes a mess when it comes up."
"I appreciate the understanding. It's probably nothing, but assuming it's nothing every time it probably is, is a fine way to get royally screwed."
Rodney nods. "That's how probability works; birthday paradox and all that." He pauses, "Sorry, the birthday paradox is a way we teach children about how enough small chances add up to be large chances. It seems really unlikely for any two people to have the same birthday but if you bring enough people together it's effectively inevitable."
"For some number of 'enough' that's a lot less than four hundred? That's not important. We'll probably go back to having my men watching often, but they won't need to be armed unless something unexpected happens and it stops being probably-nothing."
Rodney turns back to his tablet and taps on it a bit. "At 24 people it's more likely than not and at forty-two there's a more than nine in ten chance. As for me opening my mouth, they would have come up eventually, better they came out now instead of seeming like we were hiding things."
"I think I should go check for Lady Kajetana's return; I needed to ask her about something from our side anyway. If there's anything else you want to check with each other about that might be unsettling... well, here's your chance."
