Ok so I decided not to assign specific locations to any characters because that might feel restrictive and make it harder for us to meet each other spontaneously but I still drew a close-ish-to-real-life map of Danzig's historical city center and WOW GUYS EXPLORING EUROPE IN GOOGLE EARTH IS FUN?? GDANSK IS REALLY PRETTY?
Anyway here's the scrap map.
And here. Put yourselves wherever you want, depart from the actual geography of the city as much as you want, it doesn't actually matter.
The main things to note about what Danzig's city centre is like is that the space between the railway and the river is full of touristy old buildings and roads exclusively for walking, and there are in fact a bunch of side-streets, many of which lead to small parks. To the east is a maze of canals, if anyone ever sends their character there. Northwards lies a major river and then the Baltic.
The cathedral is St. Mary's Church and it's absolutely huge, so if you want dramatic rooftop views, they're just two roads away; There's also what I think is a university on the other end of the same road that's not as tall but I think has a wider, flatter roof for duelling on. don't look at me i'm not an architect
There's a long street bounded on both sides by elaborate gates that's wide and full of tourist attractions, nicknamed the Royal Road, that I'm assuming is our parade route. It looks cramped in but the scale is fairly big, so there's plenty of space to sneak around north and south of it. On its east side there's a bridge over the big canal, on the west there are highways and railways.
Go nuts, everyone. Goodnight.
