A particularly inventive symbolic pun. A "pale" in the sense used here is an enclosed fenced area, while of course the word also means dim light -- the result is a combined symbol for Unionist and unifying dream-ideals. Though Monygham too gets dim-light imagery sometimes for his dream-ideal of cynicism, this sentence from the point of view of Gould Concession personnel places him firmly "outside" their unifying ideal of progress.
