Into these she has Adarin place a portal set.
And then she mixes up a batch of suitably witchy ink that she'll be able to identify as authentic later, marks up a bunch of pieces of paper with it, and walks into: a bank.
Adarin's welcome to come along, if he likes...
Staring at a mirror, boring planet, boring planet, then -
- That is not a boring planet. It has a gorgeous sky - with silvery-blue rings, and three moons, in varying colors. One is blue, another is a white, and the last is a lighter shade of maroon. Plants come in varying colors - reds, yellows, greens, blues and other colors, some of them blending together into a swatch of one or two colors based on region, where other parts of the world they come in all colors available, all mis-matched together. On the surface, water flows freely, dividing the planet into small but numerous continents, and dozens upon dozens of island chains. After some inspection, it seems that this planet doesn't have the same hurricane problem the 'Water Stealin' Planet' did, due to what seems to be the island to water ratio - islands are so common that it's hard for any hurricane to get to speed.
It's when they're investigating the possible chance of hurricanes that they see their first set of buildings.
The planet turns out to have a lot of them, when they start looking. Overgrown cities, still standing and whole but looking a little worse for wear dot the landscape. Bridges and roads connect various islands and cities together, in disrepair and under siege by fauna, but obviously present when they look. There are no obviously visible merchants or travelers using them, though. In fact, it's like there's no sentient movement at all - the world is just still.
He checks.
"There are - I don't see any people or obviously sentient beings, but here, look -"
The scry on the mirror changes to show the immobile denizens that seem like the most likely builders of the mysteriously dilapidated buildings.
"Robots?" guesses Isabella. They're not humanoid at all - they're more like round Rubix-Cube-like things with protruding tools and wheels and objects of unclear function from half their panels, no two configured quite alike - but it looks like they aren't attached to anything and could have moved autonomously before they ran down.
"I suppose? I'm just - confused, are they just in disrepair and effectively dead, or...? I don't know how to check that with scrying."
He tries to check, then pronounces, "I have no idea what I'm looking at. I couldn't tell you if they even have batteries, not without long-term and in-depth scrying. It's just - extremely foreign."
"Well, I don't see a lot of alien skeletons, carapcaces, or chitin around, and the cities are really, really overgrown - so I'm inclined to think it's not likely they're still working."
"Yeah. I'm intensely curious about what happened there, but I'm a little hesitant to just - go visit and see."
"If it was some kind of biological problem - I'm really not getting the impression that humans lived here, however improbably similar you and I are. If it was a disaster or a war, it looks pretty thoroughly over at this point."
"True. I don't know if there's a way to check for biological problems - the air's breathable, the ground isn't toxic to the touch, but if it's some kind of germ I haven't figured out how to get a scry to get that in-depth yet."
"How can your scry tell what particles are in the air and not look at the microorganisms?"
"Mostly because I didn't know they existed a few months ago and I haven't figured how to make it do that yet," says Adarin wryly.
"Oh. Yes, I suppose that makes sense. Well, we might have a problem with diseases on any planet with an ecology. We have here strong evidence that one species went suddenly extinct here, a long time ago, but any complicated set of evolved life is going to have a history of extinctions that just don't leave artifacts lying around. This one at least has the benefit of plausible explanations like 'they had a war' on top of the unlikelihood that we're susceptible to extraplanetary germs anyway."
"I'm seriously tempted. If you want to wait a while trying to make your scrying work on viruses and monocellular life I won't fight you on it."
"It would make me feel better. I'd also like to prod my sister for a return teleportation if something goes horrifically wrong, so we're not stranded there if it turns out people do live there and they like to collect scalps."
He smiles a little. "Thanks. I guess I'll get to work on how to make scrying work on germs. We do have time, it's not like the planet's going anywhere."
"It will not. Since we're being conservative about germs and most planets that are interesting have this concern, I guess we can call it a day on planet-shopping?"
"I think so, yeah. We got basically all of the planets that meet the requirements within one teleportation of Earth - there are probably others further out, but if we want to get to those we'll have to find a planet to stay at during the interim. Which has its own problems."
