She nods, types up a description, puts a few keywords into a search bar and clicks a few of the links that come up. After 5 minutes of searching, she looks up from her screen.
"It doesn't match anything we've encountered. It's superficially like an ultra wormhole, but it's flat and has a barrier to define its edge. Bronzong's dimensional shifting doesn't look anything like that, and it's not one of the spirit world portals that Pokémon like Dusknoir favor. The edge rules out a reverse world portal, but if I'm being honest so is the fact that it brought you here, reverse world portals very emphatically only go there. It's almost certainly not one of the lake guardian's portals, especially since we don't even know for sure that they have one, and I'm entirely certain its not an inter-dream portal. Unown aren't known to have the power to pull that off at all, and if they did it would take enough of them in the area that you couldn't help but notice them. The only Pokémon we have on record with the power to make a portal that looks like that are Palkia and Arceus, neither of which is likely. Add in that the ring is pretty clearly artificial and it looks like we're dealing with humans.
"On one hand, this means we probably can't just reuse whatever brought you here in the first place; whoever brought you here seems to have gone to some lengths to ensure they weren't discovered, so it seems fairly unlikely that we'll be easily able to turn them up, and while I'll have some people keep checking it's looking unlikely that this is some undiscovered Pokémon. On the other hand, if someone else can make it, then there shouldn't be any reason we can't do the same here; it might take a while to figure it out, but now that we have a proof of concept it's pretty exciting. If you're up for it, I'd love to run some tests to see if there's anything we can figure out about the method, but if you'd prefer not to I'm much more confident we can figure it out ourselves eventually."
