Reserata Carcerem LXIII

Athwart swayed a raven 'cross land,
yon cliffs 'n' moist mountains anon 't danced
'til a callous Centuar caught her
'n' made mess ''f graces nature barters.

Ergo did sh' rhino's allure snatch,
'n' 'to confetti crushed sanity's hatch;
her new form "f rhin'cerous raven -
cloned contractions "f pain, wiles 'n' shudders.

Callous Centuar ergo tottered
'wards hankering hemisphere -
rusty raven ñ longer jocund;
jolting joy cramped b' pizzazz' dagger.

Felon fate caught rusty raven;
yore, she'd had nosy Nymphs cloven.
