'Everything' is an open area with a few other ships, a bunch of cranes and the like, some kind of vehicle for carrying boxes, and paths that all lead to a sort of processing area, an archway with a few official-looking types hanging around.
Nick goes over to talk to them, Valanda following. One approaches him and greets him.
"Good morning, officer. I'm Captain Vauners, and this is Valanda. I'd like to pay in advance for two days' docking, and inquire about transfer to a long-term slip. Got some overhauling to do. I'm not bringing any cargo off the ship yet, have to poke around the market first."
"Alright, sounds like a plan. Please follow me and we'll get your entry papers processed. We accept gold as fees, or an agreed equivalent barter in goods."
Nick makes a 'tch' sound. "I have gold."
The officer looks slightly disappointed. "Well, let's get you processed." He leads them into a room full of benches, desks, and a line of clerks at the back looking through papers and stamping things and so on. He brings them to his desk and presents paperwork for each of them, and two pencils.
There are blank spots for name, age, intended length of stay, gender, occupation, arriving ship's name, arriving ship's slip number, and a bunch of other minutiae.
