The setting is a very vague one, but it helps in understanding the poem to think of it "taking place" in three settings. The first stanza would be around town. We picture the speaker standing in dark corners when "The Owner" passes by on the sidewalk, and carries her away. Then they roam in the "Sovereign" forest for a few stanzas. We imagine it’s a dark and dense forest in which the speaker lurks. Then, the scene seems to shift to a bedroom or house. The speaker and her "Master" lie in bed together as she guards him.
