A state carved out of Virginia in the height of the American Civil War, as its people rejected the CSA and declared independence from Virginia. West Virginia is pretty much all mountains. Oddly enough, for all the loyalty shown during that spasm of internal dissent, West Virginia has become more “southern” than Virginia, complete with people in the bush, and other things. West Virginia, with its Appalachian hillbillies, supposedly preserves a Shakespearean form of English in its more isolated regions. It's also the site of the town of Grantville (based on real-life Mannington) that was ISOTed to seventeenth-century Germany in Eric Flint's 1632 series.
