Well she's just going to be aggressively polite and smiley. "From Rost? Yes."

She invites Marena in, vaguely tense.

"Alright. I swear, that man... So, where is it?"

She pulls it out of her skirt pocket and hand it over.

The lady quickly opens and inspects it, particulalry by smell.

"...Yes. Good. You can tell Rost we have it and will want more if the quality is up to expectations."

"I'll let him know."

"And ask him to send someone perhaps a bit more discreet next time. If anyone asks, though it's unlikely, please do make something up."

"I was sent for my skills in making things up." And she leaves.

This is a street full of stodgy rich person houses. She's a bold foreign probably-witch. A few of them are staring at her from their windows and looking away when they think she's noticed. But nobody confronts her or anything.

She's a witch. She belongs everywhere!

..okay, maybe not, but rich people do like, hire witches. How hard is it to say 'I hired her to enchant a thing' or even 'I am so rich I got her to personally send me a message from little Timmy on the front' really?

Maybe the old lady is just paranoid. At any rate, the city breathes around her. It's oddly much less busy today than it was on every other day so far.

Is there any obvious reason for that, or is it just inexplicably quiet?

It's mostly just inexplicably quieter and emptier.

...There's the sound of large bells ringing from somewhere.

She heads toward the bells, and hopes they aren't a warning or something.

It looks like thousands and thousands of people are crowding into churches to listen to priests talk and choirs sing!

Oh. Religion.That's a thing that exists.

She heads into the nearest church. Seems like it'd be useful for convincing people she knows what she's doing and what this society is like. (Or at the very least, working out very quickly what she doesn't know.)

Most of the people here are dressed up in fancier than usual clothes. She gets a few strange looks but the locals make room for her. Being quiet during the service is a thing, apparently.

Catholic church service mostly consists of prayers and singing (people seem to have memorized these), a reading from the Holy Bible (about being nice to neighbors even though they're nasty to you), and the priest giving a speech that's not from the holy book but about whatever he wants to talk about (hard work and diligence). And then there's the holy communion, where everyone lines up and receives a blessing and a little bread and wine. She's not supposed to do this part unless she's baptized, someone whispers to her.

Okay, this is not her usual form of religious ritual (there may be some wine, but not nearly enough) but she can dig it.

And she'll be polite and hang back with the... other unbaptised people? Is that a thing?

A few of them. They sing along with everyone all through the communion.

After the whole thing is done, the priest hangs around and talks to people at the front of the church as the cheerful crowd pushes its way toward the entrance.

Any notable commonalities among the unbaptised people? (What is being 'baptised'  anyway? Religion is confusing. Maybe someone on Team Unbaptised would know.)

More of them are non-white or foreign-seeming.

"Baptism's receivin' the blessing of the holy church, being made a member, ya know. This kind of church only lets ya do it as a babe. Bit strange if you ask me. Other kinds of churches say babes don't know what's goin' on and make you do it as an adult, promisin' to abide by the teachings. That way makes more sense to me, but here the churches are like this, so there we are."

"Yeah, that's a bit odd. Like, I can almost understanding making babies members, but only making babies members is weird. Not that it's much of a problem for me, but for other people--" She shrugs.

"Well, if you don't want to go to Hell when you die maybe you should find a reformed priest on the continent and get baptized. I'm baptized reformed, and I miss getting communion, but my immortal soul's not in danger or anything."

"If I end up there, I might do that." Read: not do that. She's pretty attached to Luna, thank you very much, and if she isn't joining another religion as part of some scheme, it's probably against the spirit of the thing.

...unless her soul works different here, so that she's at risk of this 'Hell' thing. Or something screwy happens to her exaltation when she dies.

..,she's just, like, going to avoid dying. That's rarely a bad idea.

Everyone else in the area presumably wants to avoid dying too.

At any rate, there's one last song as communion finishes and then crowd pushes out of the church.

So, that's the local religion: Jesus and singing. Not so bad, as religions go. Could afford to go more all out with the wine, but whatever.

She might go check if the post office has any more things they want sent.
