Read "Ye Shall Return" at The Eldritch Dark:
The version of this poem at The Eldritch Dark has a significant typo in the third stanza at line eleven; the correct text reads:
To see earth's kingdoms gleam afar,
Litten with promise and mirage
Beneath a mistless diamond vault;
This poem seems to refer to ghosts or other entities returning (however briefly) from the afterlife, to once again experience the beauty, the sensuality, and the chaos of human life. But such visitants can only be tourists; their proper place is not within the earthly realm:
Into the shadow-land ye left,
And draw again your languored breath
Where breathe the poppies of the dusk.
CAS packs a great deal of emotion and visual splendor into the twenty short lines of "Ye Shall Return", while maintaining a steady rhythm largely devoid of any sort of rhyme. It's an impressive work of near-free verse from a writer who often excelled at the use of more traditional poetic forms.
