Here's something that might not go over so well on the mailing list, but should be okay here!
Often I'm browing through a news site and come across a nice photo (the New York Times is good for this, though most of the photos are originally AP) that reminds me of an In Nomine setting. Take
this one for example; I looked at it and instantly thought, "Stygia."
Not a perfect match, what with the river and all, but you might say this is a view from a border near the Styx, with Fleurity's houseboat and attendant fleet passing by a small port outpost.
