A little unsure whether to post here or the Language/Linguistics subforum. Apologies if it's more suitable over there for -any- reason.
I designed this piece of poetry around a unifying theme. See if you can figure it out. I may offer hints, but as I have no idea of the difficulty level (could be instantly solved, or vice versa)
we'll have to see how it goes.
Hail, Hercules, liquefied beautiful badassery
containing no ominous fortune:
neutral, national mgmt.
Although Siamese protests support cloistering Argentina's king,
callous scarecrows, timing violent - crashing - mnemonics,
feed concubines night cures.
Znojmo gapes, gelid as secret breezes.
The science flew off Gordon Freeman's face and landed and blowed up in a BOOM!
