I couldn't find the old thread where I'd posted the garishly colourized and busily indexed version of the Corvis City Map I made when I was running the Witchfire Trilogy, so I'm posting this again for posterity and in anticipation of the new players who will be checking out the IK RPG upon its re-release in Summer of 2012.
I take no credit for the original black and white map, and all locations are based on my own interpretation of the text of the Witchfire Trilogy Collected Edition. It was useful for me as a GM to have a printed version of this handy as I ran the campaign, but I have tried to leave out major spoilers which might ruin surprises for the players.
The map isn't drawn to scale, so I didn't add one to it. But you can use a few landmarks to help gauge distances. The Black River Bridge is 2800ft (about half a mile, or .85 km) and it's 1.5 miles from it to the North Bridge (2.4 km). So if your party is on foot, it's 1.5 miles from the Quad to the North Bridge, from the Quad to the Cathedral, from the Cathedral to City Hall, and from one end of the waterfront to the other. Basically, getting anywhere takes about an hour to ninety minutes to walk, depending on crowds and time of day.
I hope you find the map interesting and practical, and welcome any advice or criticism my fellow players and enthusiasts might have to share!
