A comment that I wrote on the previous post inspired this one. Kimber An, whose blog I neglected to link here until just now, has named her muse the Old Hag. (If I recall correctly -- she has not been around in a while. I think another character offed her.) I named mine the Drill Sergeant, or Sarge. Here he is:
Yes, that's R. Lee Ermey. My muse is not R. Lee Ermey, but he looks a lot like him. Maybe a few years younger. But definitely ugly and "ate up", as we used to say in the Air Force. A great motivator.
If you could describe your muse, what would he or she look like?
