"We're going to walk into a high stakes situation that I don't know very much about. Is there anything I should know so that you don't have to suddenly issue an enforced order under emergency conditions."

"...I'm not sure I know enough about what you do and do not know to compose a useful summary. But in any case if I issue an emergency warning it will not be enforced."

"Okay."

"Mortals can die, which you've heard and seem motivated to avoid. No one knows not to give their names, or use other people's; I would prefer if you accumulated as few as possible and used them as sparingly as possible, but you may still end up learning some by accident. I can offer you an explanation of how magic works in my world, but it doesn't narrow down to a list of capabilities nearly as easily as local magic seems to."

"Those were examples. What kinds of things does your world's magic do?"

"Some, not all, people are mages. There are three base elements and three combined elements with which a mage may be affiliated. The domain of Earth is the self, and their basic power is earthshaping; Light's domain is other people, and their basic power is lightshaping; Air's domain is the world, and their basic power is airshaping. Earth and Light make Wood, whose basic power is lifeshaping. Light and Air make Fire, whose basic power is fireshaping. Air and Earth make Water, whose basic power is watershaping. Every mage is affiliated with whichever of those six options best suits them personally, which is usually one of the first three, and has that element's basic power plus an assortment of other powers associated with that element's domain or domains. Earth mages can work magic on themselves, Light on others, Air on inanimate objects and sometimes plants and very rarely animals and never people."

"Are things sometimes magic by themselves?"

"Yes in the sense that Air and Air-derived mages can enchant objects to be persistently magical. No in the sense that magical things are not naturally occurring in my world; they are all the work of mages."

"Any of them likely to surprise me?"

"Magical objects? I don't expect so. Most common enchantments are subtle, practical things, like a bucket that fills itself with water or a lamp that gives light without fire or a box that keeps its contents warm or cold."

"Will this take long enough that I should bring food?"

"I don't expect it to, but it's possible."

She packs up some food.

That seems to be everything.

"Do you want to go invisible and inaudible?"

"Hmm. Yes."

Now they both are and the boat too.

Gate's open, says a line of fairylights.

So he goes through, in his boat.

And sends to Ruava, Do you have a minute?

Korva! Been a while.

(And in the implications - she's a little distracted, and surprised both by the means of communication and by hearing from him at all, but she's quick on the uptake and doesn't need to pause to express surprise before handling whatever interesting new trouble he's bringing her.)

I have assorted magical powers, this communication ability among them, and am accompanied by an immortal fairy from another world who can give magically enforced commands to anyone whose name she knows. Where is Nirue, and what do we need to know before seeking her out?

In her rooms, in her house, thoroughly occupied and staying that way for at least another hour. You should be fine assuming you can get here without starting a riot. I'll catch you up after.

She refrains from explicitly including the implication of what Nirue is occupied doing. Korva will undoubtedly figure it out.

...

He sends to Promise, I asked my friend where to find the Wood mage, and learned that the Wood mage is currently at home, torturing her. I am going to teleport there now.

And then blink, they're outside Nirue's bedroom window, and blink, they're inside the room. There is plenty of space for the boat there. It is a large room.

And in the room is a bed, and on the bed is a grinning woman, arms red all the way to the elbow, playing with her favourite toy.

Ruava looks almost more like an abstract sculpture than a person. It's hard to believe a mortal could survive like this, but her heart is very visibly still beating.

If I tell her to stop your friend might die, she'd drop anything she was sustaining.
