A word on the maps we use for our campaign.
The larger world (Terra Secundus) map is from
several sources with extra elements painted in
on my game room wall.The smaller national map
is from our experience in the US Army at FT
Hood TX. Essentially we took a military map
of the area and enlarged the grid, so meters
became kilometers etc. We being soldiers are
intimately aware of the topography of this area
having trained on it so often.It was therefore an
easy matter to translate this knowledge to
the games table.
