Going Away Party

[Ca ne fait rien]

bitter fog wraps tilted stones
whose worn inscriptions
chuckle at strangers.

within my sarcophagus
tasting of petulance,
feral urges loiter

sweetly depredating
the rotten bond
of an immortal will.

summoned to the dance
I slip into the Stygian
like cool, clean sheets.

bitter fog mingles with tilted stones
whose worn inscriptions
chuckle at strangers

for within my sarcophagus
tasting petulance,
feral urges loiter

summoned to the dance,
I slip into the Stygian
like cool, clean sheets

LOL I did read the comments before throwing my hat into the ring.
I thought it must have been worked over before it got here, so further picking may feel a bit frutrating for you, but I'll do it anyway because I know you will take it in the spirit of discussing your poem, which is of course your poem. I too stumbled on Stygian as a noun. I can appreciate the device of Stygian as one of those adjectives where the noun is implicit, but

'I slip into the stygian
depths of cool
clean sheets'

is how ;this reader' registered it.

I also noted others were ambivalent over 'bitter fog'. Bitter and 'petulant ' go together, so what about turning it on its head and having

'petulant fog wraps ,,,'

and
'tasting of bitters' (or bitter something or other)

Just messing with it for the sake of it-
