Analysis of Chained Laments

A dark yet penetrating stare, ice like, freezing glare.
Gargoyles supposedly made of stone.
A lonely moan answers to the unknown.
Moaning inside, growling outside, chained to cold, dead stone.
Hear it? Another sad and piteous moan.

Protectors of their Master's dwelling against evil
Fending off demons sent from the Devil.  
How does this creature devise the traverse?
A Gargoyles' spirit inside is even more hideously perverse.

Yet,  it is to be used only for obedient good,
to deploy evil away from the master's dwelling of stone or wood.
No way in for evil - no way in except through the Gargoyle's jowls.
A frightening thought, for who knows what lies between teeth and bowels?

The moan again can be heard in the dead of the night.
Lonely Gargoyles chained to the stone cold dwellings, an imposing sight.
Enough has their eyes laid upon the clandestine, enough has the spirit cried,
Maybe it seeks to shed these thoughts of horror and to ease a spirit that has almost died.  

I wonder why chains of bondage, if loyalty is not uncertain?
Would Gargoyles flee and become elusive in  a rainbow's colored curtain?
Listen! Can you hear it? Laments and groans of  Gargoyles chained to cold, dead stone.

This piteous, melodic moan is centuries and centuries old.
And only the spirit within knows who or what possesses the Gargoyles' hold.
