"Of course," and they're back at the dock.

Glynda is not boggling. That would be undignified. 

"A truly monumental ability indeed, I must say, Siobhán. It is not entirely without precedent in Remnant, however. What other capabilities can you demonstrate, to lend credibility to your claim?"

"Ironwood seemed impressed by this." She conjures the illusionary globe with population overlay. "This is your planet with an overlay of the population, the movements are tracked in real time. If you'd like to test that I can zoom into just Beacon so you can test it more thoroughly. The maps are taken from your public networks. We haven't taken the time to make our own yet."

If he notices the lone dot in the Land of Darkness, he allows no sign of it on his face. He accepts the offer of a test, and examines the illusion closely for a minute. 

"I can see why James would be impressed. This is a work of impressive scope. And no small touch of art, as well." His gaze lingers on the globe for a moment longer, then he turns to Robyn. "Robyn, you have a verification Semblance, if I recall right." 

Robyn nods, waving a hand that temporarily glows green as she speaks. "Yep! Color-coded for your convenience. I can tell if someone is lying when my Aura is touching theirs. I checked with their explorer, Riley Clearsky, when she arrived in Atlas. They can also do healing, flying, and some incredibly detailed analysis, to name a few things. We just came from making some arrangements with General Ironwood for an early-warning system to teleport people away from Grimm attacks. They've got medicine and manufacturing and satellites that don't depend on Dust, too. We hit the jackpot!" 

"So it seems! Siobhán, what drew your attention to our humble realm?"

"Your world was noticed as having an unusually high death rate and some unusual magic."

"...It is heartening to learn that our troubles are not everywhere the norm. What constitutes unusual magic, in Starlight's experience?"

"Anything we haven't seen before."

Robyn snorts. 

"What is unique about Remnant, then?"

"You have dust which is a material we haven't seen before. We also haven't seen the Grimm before or activated auras. We're not sure yet if that accounts for everything we observed."

"I see. Broadly speaking, what are Starlight's goals regarding this realm?" 

"That depends a lot on what the people of your world want. In the short term, we're trying to get in touch with everyone. In the long term we want to help. We try to help societies reach a state where nobody goes hungry, stays sick or lacks opportunities for education. And where nobody dies without wanting to."

Ozpin frowns. It is faint, but it's there. 

"You claim to offer immortality?" 

"Yes. I understand the skepticism. My understanding is that General Ironwood is currently planning to test this claim with a group sent on a dangerous scouting mission."

"It checks out on the truth-o-meter! They at least think they have immortality solved. They take snapshots of a body and brain and keep backups that can be sort of re-constructed. Our Auras - they call them "interfaces", they might be the same thing - supposedly return to the reconstructed body if we've died." 

"I...see. Siobhán, would you consent to having Robyn verify your intentions? I am happy to reciprocate if you so desire." 

"Unfortunately, I have anti-magic protections that I'm pretty sure will mean Robyn's semblance doesn't work on me. I'm more than willing to test it though."

"A...wise precaution, in strange lands. Robyn?"

"Come to think of it, I never did try you, did I? Ol' Ironbritches will be so disappointed in me...anyway, here goes." She reaches out to grasp Siobhán's hand. 

She takes Robyn's hand. And it's like Robyn isn't touching a person.

"Huh, no dice. Whatever protections you got, they really work. I'm not even feeling Aura contact."

Salem shouldn't be able to disguise a Grimm as a person, especially not in his inner sanctum with all its wards...if this is her or her minion in yet another divisive plot, then he loses nothing by trying his hand at magic, and if it isn't...then he should not be operating on Salem-influenced priors, to the degree avoidable. 

"Siobhán, may I perform a similar divination on you? It is neither invasive nor harmful under any circumstances. It is merely a check for certain hostile influences. It will not go awry if it meets resistance, either."
