She listens in interest, then: "Alright. The current situation is... Complex. Some background: our society is split into nobles, samurai, shinobi, and civilians - mostly peasants. Samurai and shinobi are the ones with the 'powers,' though we have different approaches, and some civilian sages have powers, too. About ten years ago, someone started trapping all of the tailed beasts - a sort of incredibly powerful monster - and recruiting clanless shinobi. Two years ago, they succeeded in combining the tailed beasts into a powerful weapon. They targeted anyone who opposed them - which was approaching the entire world - and leveled several cities. After three days of fighting, the weapon transformed into the God Tree, and an illusion fell over the world, trapping most of those still living. Zetsu, who had been helping them fight the world, betrayed his allies, and tricked them into summoning Kaguya.
"My sister, brother, and I were among the very few not trapped by the illusion. My sister and I hid. My brother didn't, and died for his efforts. We started breaking people out of the illusion once Kaguya's attention turned elsewhere, and started an underground resistance. We eventually had a... philosophical disagreement, and split up. We've had very little luck fighting Kaguya - fighting her up-close is a crapshoot, and we don't have much good for ranged. Our main hope is to seal her, or hold out long enough - my nephew and one other boy are sort of destined to have a chance at beating her, but they're currently small children. And I'd rather not rely on them.
"Quite frankly, our default assumption is that everyone who isn't on Kaguya's side is our ally. Even my sister, despite disagreements. Immediately, I desire that you not die or be trapped, because no one deserves that. It'd be great if you and your strange magic could help us, but that's not required.
"Our powers system works on manipulating chakra - mostly our own - to have effects on ourselves or the world. There's... An awful lot that's possible, but most people stop at enhancing themselves physically, manipulating the elements, and placing or breaking illusions. The Uzumaki clan have also been insisting we all learn more sealing - it's math-based, I'm not very good at it, but you can do everything from sealing things in a scroll to teleportation with it. The long-distance communication is an ability of the Yamanaka clan - they have mind-affecting techniques, that with the right tools and preparation can be generalized into telepathy. The truth-detection is mostly a Mariko thing, she can sense chakra fairly finely and tell from changes when someone's lying or telling the truth."
"If you want to learn how to use chakra, we're currently teaching the children, you could sit in on their classes."
