Thanks Viking! There are city gates though the slum area isn't in the area surrounded by the city wall. The walls don't circle it because slum area is on a mountain/hill side. To know more details about it, you'll probably have to ask the client that commissioned the map ;)
The map is absolutely splendid!
And I agree with Viking - "the border, compass and other overlaying details" are a masterpiece.
By the way, Bhirma is (or was) a real city in India - it would be interesting to compare it with the map ;)
Thanks much Gallien :) As far as I understood, the game is a fantasy setting in ancient India.
