Stained-Glass

Stuff I relish (not sure if that's a good thing) - the stuff of bad dreams and outrage.
And yes - I agree with Leannes suggestions.
If you decide to got with 'where shadows flock to dwell', you could pair it with 'where shadows bleat within' (S1), which would also enhance the rhythm/meter.
Unsure about that last line 'fix' - perhpas something like 'in purest stained-glass hell'? Or even 'as one in stained-glass hell'. (?)
I notice this has had a large number of views in a relatively short time - not surprising, having read it.
