Sadde's running.
Not for any particular reason, just because it's faster. He's been meaning to go to one of the capitals for a bit and now, he supposes, is as good a time as any.
And eventually he's not running anymore, because he's close enough to civilisation that someone might spot him. Not that he wouldn't be able to notice them by scent before they saw him, but still. And as he makes his way to the Norway capital at this more leisurely pace, he notices the tiny, shiny key. He walks towards it and picks it up and immediately notices just how magic it is. He can tell by the way the key feels like things, and different things depending on where it is.
He verifies that what the key feels like is consistent in absolute location by waving it around a bit and seeing that the same place always feels the same. "Huh," he murmurs to himself.
He straightens up and thinks. The first obvious thing to try is seeing whether it opens any doors—a universal skeleton key sounds like the kind of thing a magical key could be—but the second obvious thing can be tested right there and then. He pushes the key into thin air with some purpose, as if he wanted to unlock an invisible door, and then turns it, et voilà, the faintest of door-shaped outlines appears before him.
He locks the door, and it disappears. Unlocks it again, and there it is. So he pulls it open and sees—
"Exactly how much sex do you need to have before you can spend more than a couple hours at a time thinking about anything else, I'm honestly curious."
"...that's not really how my brain works. I can't generalise from my own experience to other vampires, but given the number of thoughts I can have going on at the same time, and given that I'm mated to you, I don't know if there'll be a single second for the rest of eternity I won't spend thinking about having sex with you at least a little. That said, it's not nearly as much of an insistent priority as it was when we met."
"I mean, I'm not spending my average day doing anything especially productive and sex is certainly a pleasant pastime but I do like variety."
She cocks her head a bit. "How do you feel about not doing anything especially productive all day?" she asks.
Shrug. "I take a lot of summons in the hope that one day I will get to terraform Mars, and in between lament the fact that I peaked at, how old was I, nineteen?"
"My greatest accomplishment was a century and a half ago and I have no opportunity to top it, it's frustrating. I mean, it was a pretty damn great accomplishment, but still."
"Yeah I'm starting to get why my magic thought I'd like you, what was the accomplishment?"
"...I just had this sudden very strong urge to kiss you. Of course you're awesome."
"Thank you. But this was a hundred fifty years ago and I wasn't quite anonymous enough and some asshole shot me in the head, so."
"I mean, I haven't been literally sitting on my tail re-watching Atriama the entire time, but that was definitely the highlight."
"We should fix that. We should definitely fix that. I wonder how many tries I'd need to open a door to your world, we could get you to terraform Mars. Or maybe find a way to mine and bring standards of living to 2159's, I'm sure the Empress Regnant wouldn't mind. Also I wonder if I could summon other daeva from here, not being a demon but not being a human either."
"And they have all done so. Although the early twenty-first century probably needs me and is less likely to shoot random people trying to get rid of me than current Mars. Where I'd actually really like to go if we're on general flights of fancy is Limbo. It's flat earth and one thing per person and that's it. And I could see my parents."
