Grimrock

That map looks pretty unusual. I would have expected messier borders. This way the two realms are either very closely matched in power or not very warlike. Otherwise I'd expect a river or other chokepoint to be the border.

Hello,
I was wondering if there's some official lore of Grimrock. Already read the handbook and found the map. While that's all pretty interesting, it's just so little. So, did I miss something apart from some ingame descriptions on items and treasures?
