The Map by Zak Schooley is the semi-circled one. Got low and high res maps.
I placed them here in a page with Chainsaw's map (slight work with Photoshop, but nothing great) is there and Tim Callahan's map Ghul posted in that other section.

I used Zak's map and stole (I mean borrowed) stuff from many sources, Rat in Wall, Chainsaw's, and his taverns and inns and from above Tim's map. (see map with grey sea added which is named locations also) Plus a few other sources like the Charnel House by Eirvit and some PbPs that mentioned a tavern (cannot remember name of it). Oh, yeah flooded city as Chainsaw's idea, but evil Neil, oh yeah that me drowned the Amazon District.
Still had to changed scale as Zak had 300 feet, and I needed to make 1,200 feet to stretch to 6 miles across, which ruins scale for buildings, hence argh! Building sizes are wrong, etc. and they would be gigantic, but one must presume to zoom in mentally to appreciate the structure of map and forget the error/change in scale.
As it is Jeff that stated 6 miles across for city, that should be official, but I also have started (but not finished) one about 15 miles wide to fit the whole peninsula. I place also, but will take years to do, I in no rush... (placed for show only as it incomplete). I created a city built by the gods for the gods (that is the outer gods). When the Hyperboreans returned, new land had formed to south (because of the crushing ice) and they commenced to build more non-alien structures of Hyperborean design. Later again the tribes took Khromarium and the more southern buildings are of their design, not yet done (on map), but note palisade wall around harbours. Black = old city, grey = Hyperborean and lighter grey = Common men.
Of course stole ideas, Chainsaw should recognise his inner harbour is traced and added... and tried including Tim's main river, etc.
