A lost kingdom

Down by the back of forgotten alleys,  
Where only the lost may wander.  
Behind boarded up red brick ruins  
With graffiti walls and grassy driveways.  
There's a canal,derelict and decaying,  
It's water septic;toxic malevolence.  
Armadas of ancient plastic bottles  
Caught in stagnant slime green purgatory,    
Black putrid moss is climbing up,  
Crumbling cement walls.  
Trying to escape it's wretched prison.  
There noise somewhere;i turn to see,  
A crow perched upon the lock.  
It's claws sending flakes of mouldy paint,  
To lie upon foulness down below.  
It scans its vile horizon and croaks into the dreary sky then flies into the air.  
Landing in my way; strutting around like emperor of decay;  
Warning me with eyes as black as the most twisted soul,  
(giving my legs a sudden urge to run),that this is no place for strangers.  
With a flap of his wings he returns back to his throne.  
I step over discarded syringes and burnt tinfoil  
and leave this squalid place.  
Where even the demons have abandoned all cause for hope.
