Lotus didn't start the fire - that was probably the dragon, she doesn't know for sure but it's the most likely hypothesis given, you know, dragon - but she was ready for it. She had gone for the library, joining the foolhardy, heroic-minded individuals rushing in and out to save the books. She had grabbed the books she needed and then raced across the campus, heading for the teleportation circles. The building is unguarded, for once - not surprising given, you know, dragon - so she slips in. She picks the nearest circle, disrupts it so it will pick a destination at random - should make her harder to track down if that's anybody's priority given, you know, dragon - and steps in.
"...You and your God must be much more constrained in your ability to communicate than my gods."
"And yet here you are, talking to me. Has your communication ability improved or am I just that important?"
"Angels don't typically come to Earth because the transit is--risky. For reasons I forbear to mention because obviously the risk of a thing happening goes up when more people know it's possible. I don't have any particular reason to mistrust you, this is just a general policy. We're here on Earth now because of the new Christ."
"Risk only obviously increases if it's a thing people do, and wouldn't normally do by accident. If I were to speculate, I'd guess that angel parts - blood, feathers, hair, eyes - are magically useful or something. I am probably not going to cut you up for parts."
"I also can't think of anything productive you could do with the information. If I were to tell you, I would want past-scrying wards at least as good as Kanimir's and without the exception for him doing the past-scrying, which would be very difficult to attain."
"I am not expecting you to tell me but I may keep trying to find out because of who I am as a person. How does past-scrying work?"
"Does it require the caster to be in the place to be scried? If not, does it work across planes?"
"As far as I'm aware neither hard limit applies to the system but no one has figured out how to do cross-plane scrying."
"Well, until someone figures that out I am pretty sure I have access to a past-scrying-proof area, in case there are other conversations you want to have in private. Though I suppose I haven't confirmed that I can access it from here."
"And something that's past-scrying proof by virtue of no one figuring out how to scry there stops being past-scrying proof when they figure it out."
"The space in question seems to also cease to exist after use, if that effects things. I will also work on anti-scrying, that will probably be useful to have anyways."
"There is a spell in my magic system that creates a very small plane that lasts for a number of hours. It seems to be a different-but-identical space every time. I suppose if you happen to know a past-scrying spell we could probably check if it's the same plane every time, somehow. Once the spell ends it can't be accessed anymore, even by more powerful planar travel spells, so it probably stops existing."
"It'll take me fifteen minutes to prepare it, let me get my things." She runs off and returns shortly with her spellbook and a coil of rope.
And after about fifteen minutes of reading her spellbook and muttering to herself, she stands up, chants some words, gestures some gestures, and tosses the end of the rope into the air. It sticks. She climbs up the rope, disappearing from view as she passes the top of the rope.
Her head pokes down into view a moment later. "Coming?"
Inside is an approximately fifteen-foot radius hemisphere bounded by mists.
"Oh, wow, wings. I was wondering."
