"What an odd mistake for them to make."

"They were attempting to prevent a plague from spreading. We had a difference of opinion about what methods to try first."

"Ah.

If we exist in your world we could probably help with tactical support. I don't know if we do, but we'll be able to check shortly."

"Might be worthwhile."

"I'm tentatively guessing not because I think we would've interacted but maybe our path there is different just like yours is."

"And what was your path, exactly?"

"We learned in 1970 of the existence of supernatural entities disguised from the rest of the world by some magic that makes it hard to notice or correctly attribute their behavior. We did some research and began working with the U.S. government to establish diplomatic relations with those demon societies organized enough to largely abide by the terms of treaties negotiated with them, and to protect our population from those demons not inclined to obey such treaties. We started an interdimensional refugee resettlement program and opened bases of operations in cities with particularly high supernatural populations, including Los Angeles. We got involved in operational support of the Slayer, the existing forms of that being inadequate. We're currently working primarily on the retrieval of our dead citizens from hells. We're formally affiliated with the U.S. Bureau of Environmental Enforcement."

"Never heard of it. I'll be moderately surprised if it exists."

"It isn't supposed to be widely known but I'd be surprised if it never offered you any help at all with this situation, yeah."

"I would expect to have learned about it before I left the Watcher's Council. Unless this is a very recent arrangement, I suppose, given that they were blown up around six months ago. But it sounds like our timelines have drifted further than that, if they were ever identical at all."

"In our world the Watcher's Council has definitely heard of us, yeah."

"Where were you before 1970?"

"Ouch, do I look that old?"

"Everyone's from somewhere."

"Our species is native to Azerbaijan. I was born in Kansas."

"I find it interesting that a race of demons would be surprised to learn of the supernatural. But perhaps you thought you were the only ones."

"We thought there were four sub-species of humanity, and one universe, and no magic."

Nod. "Well, I don't have much experience with other universes - besides Pylea, Lorne's home dimension - but perhaps our science team can tell us more about this place."

"Just Fred, I hope? I really am worried about Wolfram and Hart using this to expand to corners of the multiverse that have avoided them so far, or to make their operations across dimensions simpler."

"Angel?"

"She wants to bring Knox."

"Tell her it's a delicate situation and we'd like to keep the circle as small as possible." - he is not supposed to be the one giving orders. "At least if you think that's an accurate summary of our  priorities."

Nod.

"She'll be right down."

"Thank you."

She arrives shortly thereafter.

"You guys! Do you have any idea how rare stable transdimensional portals like this are? If that's what this is, it could be some lesser variety of spacetime-warping phenomenon, but - do you have any idea how cool this is?"
