After all this talk of Maps, I've posted a big one. I hope you all can see it. I wanted you to be able to tell where you are relative to the nearest enemies. (And Zasha, too, who is up in the top left). There's a few people just off the map. I forgot to mention that Averiel climbed down off the palisade and is just behind Dandin on the bridge.
I've been playing a little silly game in my head, role-playing what's going on at the other locations. A few goblin in-fights, trouble loading the boats, that sort of thing. So as not to bog the game down with too much information, I've only shared a bit (like Zasha and her pursuit) but the Julkounians are stubbornly not going quietly (while trying not to get themselves killed). They are valuable slaves, so the hobgoblins are disinclined to murder them, unless they get *too* annoying.
Just at the bottom of the map on the right, there's a hobgoblin bannerman and a goblin bully who have been sent to see what's taking the next load of prisoners so long to get to the boats. There's a chance they'll see you this round, though with the dark and the rain, visibility is not very good.
The goblins leading the prisoners are carrying torches (for the benefit of the humans, and to look intimidating) so that group is easy for the characters to see, and the characters are generally aware that there are enemies toward the docks, but the specifics are not too clear. Darkvision is only limited-useful, between the rain and the distance.
Near buildings (within 5 feet) there is darkness, and in open spaces dim light, if you want me to be somewhat "official" about it. Use your imagination, I'll generally not fault you for it.
