Thanks are appreciated, praise unnecessary. Regretfully, his ability to cure the sick is limited for now, but he'll be back again tomorrow. 

(He's going to have to do spell research to reinvent draconic remove disease, isn't he. Ugh. Well, he does like personal growth and he's got to start somewhere if he wants access to more niche spells than his usual fare. Long-term goal, though.) 

Goodbye weird dragon!

He waves a claw and takes off to spend the night in the clouds. 

The clouds politely continue to exist all night.

And he doesn't get attacked while sleeping even once! 

In the morning, he plans to sound out the local equivalent of a merchants' guild, if one exists, about their prices for rapid transit and shipping to various cities. It's never too early to turn a handful of daily teleports into fabulous wealth (and spell diamonds.) This info can inform which locations he attempts to familiarize himself with first. 

(A local branch might not have the info he needs ready to hand, it's a weird hypothetical unless they have teleport-capable magical girls, but hopefully they can at least give him a few guesses and tell him who would know more.) 

Nobody seems to have heard of a magical girl who can teleport but it is at least not out of the question as a hypothetical. They can offer him a lowball, at least. (If questioned on this figure they point out that he's weird and they don't know if he's reliable.)

That's all right, he's just aiming to get an idea of which cargoes and destinations to prioritize, since he should visit each destination city in person first. London's on the list, that makes sense. He gets a variety of numbers.

...some of the numbers are for transport of slaves.

RIGHT THEN. Are there, by any chance, a group of people — perhaps religious people — pressing for an end to this practice? There are? Good. 

Time for an impromptu trip to London to talk to the abolitionists! He can get there in just a few hours if he flies hard.

As usual no one is alarmed by a dragon flying around as long as he doesn't say anything.

Then no one will have cause for alarm until the dragon lands in London and starts making polite inquiries about where to find the abolitionist faction of Parliament. 

Why, is he going to eat them?

No, he would like to help them. Slavery is awful. 

How exactly is a weird dragon going to help.

Good question! He plans ask the abolitionists, after explaining his particular weirdness. But he's new to London and would appreciate directions.

Well, the halls of Parliament are that way.

Eh, close enough. He'll head that way and continue his polite inquiries. Presumably they won't let him in the building immediately but someone ought to at least know who the abolitionists are and where to contact them...?

He won't fit in the building! Are there specific abolitionists he wants to - write letters to or something -

Oh, he can get smaller for a while if he needs to. But as a first step, he'd like to know who the abolitionists are, and perhaps get a message to them that a powerful magical creature from another world wants to talk about aiding them in their quest against slavery. He can meet them outside or in a park or something, whatever's convenient, or shapeshift if he's invited in. If they happen to have ink and paper he can pen a note. 

Uhhhh they don't really have a procedure for someone who vaguely knows that there are sympathetic MPs but does not know who any of them are to walk into the halls of Parliament, especially if someone is a weird dragon.

Yes, this is reasonable, he is fine with leaving a note or something. He's hoping someone here has some idea who the note should be for. 

Somebody volunteers a name and nobody immediately contradicts him?

Excellent, thank you! Is this the most prominent member of the abolitionist faction, would you say? Would anyone be willing to carry a message to this person, by chance? 

The same guy who gave his name says he'll drop off a note but is not sure that you can really judge things like "most prominent".

He doesn't have ink and parchment, so he prestidigitates both and pens a short letter introducing himself, indicating he will be in a nearby garden for the next few hours. Then he goes to said garden and chats with passerby. 

(Ipaxalon is aware this is unorthodox. But figuring out and then following whatever their procedures are could take weeks, and if he were an abolitionist and a high-level adventurer showed up eager to help, he would want to talk to them immediately. He'll attempt the long, slow, formally correct approach only after the obvious direct way fails. At any rate, being very visible and chatty in the middle of Parliament's garden should filter for the sort of people who actually want to talk to strange talking dragons and might be inclined to help. If nothing else, he bets he'll draw a crowd and someone who knows someone will eventually wander over just to see what all the fuss is about.) 

He does draw a crowd. Every time someone hears him talk for the first time there's a pretty substantial chance that they will run away.

Before he sees any results from his Parliament note, a magical girl alights near him. She's got blackbird wings and feathers in her hair and a black-and-silver outfit that trails behind her in the air (she blinks and shortens it right before she lands).
