The Last - Dagon

From the wharf that night I saw it crawl onto the stony shore
And from a crevice in the rocks it pulled a hat and coat
And in the guise of man it shambled down the boardwalk in the dark
Primeval rumblings in its throat
The last 4x
Its luminescent eyes peer in the tavern by the docks
Where sailors spend their leave and dance with village girls
And when the dancers kiss it pounds its fists in angst against the glass
The lonely last of a long forgotten world
The last not quite man
It lives within the sea
The last final son of some aquatic breed
The last we'll never understand its wretched pain
The last the life we share the ecstasy it craves
Its scales abhorrent worst of all creation
Its cries a tortured mind's emancipation
Its form inverse of common decency
Truest terror of it all anthropomorphic similarities
Its people died out long ago
A holocaust we'll never know
Target of extinction
Nature's own malediction
Lusting for our human pleasures
Twisted longings beyond measure
Memories exhuming
Painful past consuming
Explanation：
The last is written from the perspective of a man who lives in a seaside new england town
He tells us the story of a creature he has seen crawling out of the ocean
We come to learn that this creature is the last member of an aquatic species that has all but died out
Little is known of what happened to them
But the narrator is able to tell us quite a bit about the individual he has witnessed
The creature
Left utterly alone
Longs for the companionship it sees in our human lives
But is denied because of its horrific appearance
Scaly
Dripping
And creeping on webbed limbs
It must disguise itself and move among us in the dark
But
As the narrator tells us
Truest terror of it all
Anthropomorphic similarities
The most frightening aspect of this beast is just how close it comes to being human
