Can he give her, like, the largest number he can find in a quick internet search as the bar tab for a lot of interconnected suites. Like a hundred of them.

Sure.

"I do not want to stand here for a year filling Bar up with the densest available currency over and over."

"My society does almost entirely electronic currency, wouldn't a money order computer chip that fits the number on it do?"

"She can take counterfeit, she can't take things that would be connected to an account of some kind and actually aren't."

"If time goes way faster for them than us and their grandkids come down after a hundred years because the room's not paid anymore and run into a grey -"

"I was assuming they'd have to come down with more subjective regularity or at least interact with somebody who can come down, for like, food. An angel can change their hair."

"I was going to teach them summoning so they did not have to come down for food because they might run into someone."

"They can also send a summon downstairs to dump more counterfeit on Bar, then, if that's what they want to do. What are you thinking they'll trade?"

"They can breed cute local animals."

"That will not work indefinitely."

"It's kind of impossible to plan time-related stuff in this place. It might work indefinitely because practically no time passes in the daeva realms between their summonses, it might work indefinitely because thousands of years pass and the daeva strains have evolved, it might not work."

"Daeva strains evolving won't help, if they have anything reasonably closely related they can knock it up with heirloom embryos."

"In thousands of years there could also be an accident with a black hole. The point is that it's really really hard to plan."

"Yes."

"So I'll get them some cute fluffy things and a list of demons who want to learn their language and hopefully it'll hold them until there's a better solution for reds generally and if not we can figure things out when we have more specifics."

"Maybe I can keep them electronically synced."

"That'd help."

Cam codes up and tests a thing. Seems to work.

Telkam visits Isel's vacation place. 

It has reds in it. The one with purple hair is bringing in the groceries.

"Can I come in and talk with you all for a bit?"

"...yes sir."

He heads in. Is his well-paid translator there.

Yup, there she is. Translating, even.
