Vermin

Hordes of disgust
Hungrs, hasty, roaming at night
Red eyes leering
Apparitions of the darkest kind

Heinous rodents
The past of the modern
Agglomeration
Living terror

Indestructable abominations
Symptoms of the fulminant deseases
The number of infected ones
Increases

Inimical towards the human race
Death in it's most efficient way
Ghastly creatures
Enticed by decayed filth

Abjective vectors
Crawling in fermenting dirt
Seat in stinking slime
Malicious horror

Still unaffected by time
Spreading an awful and deadly
Zymotic
Whole parts of mankind
Contaminated

Bubonic plague, immortal enemy
Several populations attained
Verrucous corpses lie in the alley
Mephitic cadavers are rotting away
The livin covered with furuncles
Vermin, infesting another decade
