It is during these restless walks from dusk till dawn, peering at and examining whatever takes his fancy, that he sees and realizes things he's missed, about himself and the world. It is as if the secret corners in his head were being slowly illuminated, corners he never knew existed.

The Hermit's staff leans out before him, not behind. And it carries a lantern, not a pack. The Hermit is like the lantern, illuminated from within by all he is.
