One such arrival is a man in notably fashionable clothes, standing with a very odd sort of posture - sort of a cross between standing up tall to ward off threats and preparing to run at any moment. He, like many, is looking for the power to control his life.

The city, at first glance, is dark and crowded. Further observation does little to dissuade this impression. 

It is certainly that. The night air is warmish, and smells of... well, a variety of things. There appears to be some kind of fried seafood being sold in that direction. If he would rather drink, there is a flyer posted for the Singing Mandrake, a bar of some repute. If he has some other destination in mind, of course, the world is his oyster.

…his first instinct is to find somewhere less.. lower class, but that’s not necessarily a good idea in this situation. What do the options for inns and housing look like?

There's a lodging-house visible from the docks! There are presumably others, too, deeper in the city.

If he's prepared for his trip he may have a map of the city, which vary in licitness based on how detailed they are. A map that can get you from Spite to Watchmaker's Hill might get you glared at by the constabulary; a map that tells you how to navigate the labyrinthine backstreets will get you fined considerably. However, any map worth the name can get him to somewhere higher-class than Wolfstack Docks.

He’s not an amateur, his perfectly-legal map unfolds into an actually useful map, which he’s nearly memorized by now on the ship here.

He’ll go somewhere a bit higher-class, definitely. Not upper-class, but somewhere that has rooms that are clean and have a pretense of security.

Veilgarden it is!

Veilgarden is a place of starving artists, but they have dignity. A Veilgarden hostel will certainly have clean rooms, and the higher-end will have locks on the doors and windows, which is about as much security as he's likely to get.

Artists, really - well, needs must, and this seems the best chance of getting a clean room. He buys a week’s stay, sets up some basic traps on the windows and his belonging’s (after telling the room service what not to touch, with a few extras to make sure he’s not just clarifying what’s valuable to him), and goes to sleep. It’s been a very long day.

When he awakens, it's no brighter outside. Naturally, as the night never ends in London.

What plans does he have? 

Well, first, he’s going to get some breakfast, and look at people to see how the fashions differ here from on the surface while eating. Are there any reasonably priced and clean places to eat nearby?

There are definitely reasonably priced places to eat nearby!
