" - uh, build lots and lots of stacked tiny cages to raise them in and breed them to grow very fast in those cages and cut off their appendages so they can't self-injure in the cages and douse them periodically with noxious chemicals that give them chemical burns because it's cheaper than cleaning the cages? That's a thing lots of places end up doing."

"I'm not sure why you'd cage an oyster."

"That's mostly for birds, do you not eat birds?"

"We don't eat birds!"

"Then this is yet another area where you and the Valar will not find yourselves at odds."

Sigh. "Okay."

"You can let us know if there are problems but I really do not anticipate any."

"How do I get ahold of you without teleporting to a dot?"

Address labels! "Write anything on this piece of paper."

"How's that work?"

"We have some demons working for us who already know about your world and can conjure regularly for mail addressed to them, which is what the characters at the top of the page are doing. - it looks like conjuring writing from your world doesn't get anything you've burned, so if you burn the contents of mail you send us this won't work."

"Huh. Okay."

"Pleasure to meet you."

"You too."

And he heads back over to the portal and through it into Milliways. "Egg rogue - her name is Tireh - seems an eminently reasonable person and agreed to stop it with the daeva if we give her a better mortality solution. A Vala can handle it, there's only thousands of them."

She follows him and peers under his arm. "You've been calling me 'egg rogue'? And there might be more than that, I haven't counted, nobody has."

"We've been calling you egg rogue and your world egg world but you are entitled to suggest other names, and encouraged to suggest ones that don't call attention to the thing that makes your world dangerous. Tireh, this is Timothy, Minor, Cam. You should also meet Ambela, she also invented writing in her world."

"And Mingling's Fëanáro, he did too."

"Beach," she says.

"Lovely. This is Milliways. We don't usually portal directly here - there's a planet set up for portals, and we'll put one there for you - but talking to you before you summoned anyone sufficiently curious seemed urgent."

"How come you don't portal here?"

"This is a place where a dangerous person could do a lot of damage. The portal planet is designed to be much less of one."

"You seem to have a lot of vulnerabilities lying around."

"I agree. We have arrangements now to check for and detain interdimensional tourists."

"That would've been fun."
