Cult of Dagon

Decrepit buildings on the seaboard of this town
[?] while few are still around
Disfigured [?] with a secret not to tell
Assembled at the black church where they (took) the vow

[?] fills the chapel when the sun goes down
The high priest finally emerges with the two-pronged crown
The preachers advocate faith from long ago
And speaks of [?] the undertow

Late at night when the full moon is shining
Out on the [?] and the [?]
And you can hear perverted words vibrating
The sacred rights have been initiated

The offering is almost dead and bleeding
The air is sharp so they commence with breeding
They copulate with the submerged while seeding
To ensure their god continues feeding

I can't tell if I'm awake or dreaming
I hear the sound of something awful screaming
[?] of centuries of mis-redeeming
Awaken aliens of cosmic being
