Tanya has no problem standing watch for two hours in a cool and quiet room. Even with her attention carefully trained on the door and any magic she can sense near the room, this leaves her a lot of free time to think.
She is in another world. Her third, but she didn't reincarnate this time. It could still be Being X setting her up, but probably isn't; if the locals think they have a full explanation, with precedents, then Tanya has no reason not to believe them.
On its face, this is absolutely excellent news. She no longer has to risk her life fighting a doomed war! She is free from Being X placing her in ruinous situations! Even Earth might be free from Being X making mortals irrational, which Tanya half-suspects he was doing to annoy her! She got her retirement handed to her on a golden platter. The dragon's hypothetical family is a real concern, but it can't be as bad as being a soldier, she'll clear it up and then go on to be a productive member of a peaceful society! Even if all her non-combat skills are irrelevant or obsolete on Golarion, thirty years' worth of pay will let her start a new career or three.
Complication: it might be possible to communicate with Earth, or go back to it. She might even be forced to go back to Earth, if not immediately.
As long as going back is possible, Tanya's duty as a Germanian soldier is to do so. She is conflicted about this, obviously, but it was always possible to betray her comrades and the Fatherland and run away, defect or just hide in another country. She never seriously considered doing so. Being on Golarion gives her more options, but she's not going to abandon them the moment she's out of sight.
If she goes back, she'll bring novel magical technology with her. Revolutionary technology. Technology which, in the hands of Germanian R&D, might yet turn the course of the war at the last possible moment. Or it might just make the war last an extra decade and kill or maim half of another generation's worth of young men. Still, that's not her decision to make. Lt. General Zettour might have the rank and position to make a judgement call like that, but as a mere Lt. Col. Tanya emphatically doesn't.
Ongoing communications between Earth and Golarion would be much more useful still, but they raise the prospect of other people making the trip and that is dangerous. When a technologically superior civilization - worse, several planetsful of different civilizations - make contact with a less developed one, the results are often grim. It would be best if they could keep to sending messages until Earth catches up, with Germania (i.e. Tanya) relaying all such messages. She doesn't know how to prevent Golarion from leveraging communications into interplanetary transportation, but she will avoid suggesting or promoting it.
If she stays on Golarion, can the locals still contact Germania with her help? She isn't sure and will ask Nazir later. If that works it would be the best of all worlds: an excuse for Tanya to stay here as a relay, possibly an invitation to bring more Germanians over to relieve her (she continues not to be an authorized diplomat and must not be construed to usurp that role!!!), and communications that may benefit Germania on the other side of the line. In fact, it would be best to establish a permanent Germanian delegation in Osirion, to make sure their interests are well represented and to help smooth over any cultural misunderstandings. Negotiations are always best conducted in person.
Transport from Earth to Germania has been demonstrated; the other way around has not. Tanya would be very gratified if this state of affairs continued.
After two hours have passed, the rope trick fills with the sound of Tanya chirping(*) 'It's been two hours. Iomedae, please wake up.'
