It's still unlikely that there would not be any buildings that were only houses.

And that font on the map, it's pretty interesting, but impossible to read if you don't know what it says beforehand. Otherwise it looks like Amskmr, or, if one happens to be knowledgeable in runes, you can get as close as "Aesker." But I can't see anyone being able to look at that and see "Vesper."
