The Marches are a "Generic Place Holder" I use in various posts. It was not meant to be a true place, but I have used it so often that it is evolving into one.
Some general ideas about The Marches
They are broad and mostly flat.
Some occasional streams run through it.
They are somewhat inhospitable.
They are surrounded by mountains
They are relatively recently "civilized", as civilized people have reached their edges and only recently have begun to truly invade it.
It could be on "The New World"
I see it in the center of things, a inhospitable place forcing people to be around it.
The Orcen call them home.
