This came to me yesterday and today as I was in the car. Just a couple lines, nothing much. I envision this character as a tall, skinny man. He wouldn't be a main character, more of a guide or advisor to the main characters that pops up from time to time. Anyway, here goes:
Some people recon that there isn't an inch of ground on Earth that hasn't been tread upon by the Walkin' Man. Some recon that he's been walking for a long time, maybe for all time.
