On the map of Lave ....
I too have been needing this, as my players are going to be eventually playing in the Serpent series of modules. Knowing my group, when they get to a city, they want to do and see everything.
So, I was stuck. Until I opened a book I had for quite some time, on my shelf.
Seven Cities, by Matt Forbeck, published by Penumbra.
EXCELLENT DM's accessory. If you dont have this, get it. 7 cities, from small towns, to large cities, all keyed. As larger cities are used, the keys advance with the map.
Now, for the Lave map, for those who have this book, I'm using the Large Town.
The SLCS: Ghelspad book says that Lave has 30K people. The Large Town in the 7 Cities book (page 87) says it accomodates about 5K people.
This doesnt bother me, as my players aren't going to know every detail of Lave, just the top 20-30 Poi's TOPS. I can use the Large Town map as a layout, and make the city of Lave seem like it holds 30K people.
But the layout of the Large Town is perfect, with the river on it's east side. Most of the generic keys are fine too, and one can easily overwrite a few keys to match THEIR rendition of Lave.
