He's curious about the typewriter, and declares it clever when she demonstrates it and asks where he'd get one.
Fharlanghn is the god of travel, freedom, trade, and cultural exchange of his world, which has lots; he's an intermediate god, so not one of the major powers, but a household name in most of the world. He teaches that it's important to expand one's horizons, to learn about the world and find one's place in it; even if it turns out that you belong back at home, going and seeing what the rest of the world is like will still teach you valuable things that you wouldn't otherwise learn.
The other obvious difference between this world and his, besides gods and the lack of magic here, is the lack of different species; if he spent a day walking around a city this size in his world, he'd expect to see at least a dozen kinds of people, but he hasn't met anyone here who wasn't human.
He's not a scholar, so he doesn't know much about cutting-edge science in his world; it is substantially more technologically advanced here, though. He doesn't have any complaints about Port Prosper - rarely dislikes places at all, he'll say, if she pushes - and the views are gorgeous and the people friendly and interesting; he hasn't seen anything too shocking so far, though everyone being human is definitely weird for him. He's looking forward to the feast; he loves a good festival, especially in a new place, there's always so much to see and do and learn.
His repair spells are well known to be reliable, at home, though of course they only have his word for it and a few days of evidence, here, and he wouldn't blame anyone for wanting to wait and see. That said, if anyone has something for him to do that the mechanics can't handle, it'd be wise to let him know soon even if they do want to wait before having him do it; clerics of Fharlanghn never stay in one place for long, and he might not be back soon if he doesn't have a reason to be.
He demures, about the praise - of course he's doing healing, it's some of the easiest magic for him, and the highest impact for everyone else.
He is from another world or at least another plane; he can confirm that with magic, he has a few spells that work at any distance within the same plane that don't work between here and the places and people he's familiar with. He's not sure whether his god was involved in him coming here; Fharlanghn usually asks rather than just doing things to people, but might not have had time to if the accident was necessary to allow it and it caught him by surprise. Raafi doesn't think Fharlanghn is the same sort of being as the stars, but he admittedly doesn't know much about the stars or why they think they're people, here - they do have a god of the sun, at home, Pelor, who says that stars are distant suns, but other gods don't have any particular connection to the sun and anyway there's a difference between being the god of something and being that thing, probably.
He's really not trying to make a political statement at all, working with St. Cavendish; they were the first hospital he came to and they've been keeping him busy enough that he hasn't felt the need to go find another one to work with in addition. He'd prefer people go through the hospital to arrange healing, it's more convenient for everyone that way, but he has no particular objection to someone contacting him independently if they feel they need to.
One of his more powerful spells does let him turn into cloudstuff and travel on the wind; he hasn't used it here and doesn't use it often in general, though, mundane ways of traveling let him see more of the world. He's never heard of the Liberation of Night. He is human, though of course if he were a transformed dragon or something he wouldn't admit to that.
