"The Cathedral of Bones"

Low and behold the cathedral of bones;
From which I hear many nefarious tones.
Murderous hymns well up from the deep;
In which cadavers, bones, and demons
Sleep. Vigorously chopping, hacking, and
Mutilating the bodies of old; down in the
Labyrinth so deep so cold, Constructing
The foundations of the very walls;
With masses of pearl skulls. Droplets
Of scarlet fall from these corridors
Of gore; scarlet blood falls begin
To pour upon the deceased, the bones,
The diabolically diseased. Seems the
Dark lord was not at all pleased as the
Scarlet torrents befell and destroyed
These diabolic diseased; seems their
Blackened lord held them in much
Contempt “I shall bury thee” he said;
Upon this they were all of them dead.
