A great story. Very good.

Brilliant. A quiet, reflective piece, and almost painfully good. It gave me chills. Well-done.

This 'phantom' man without a name is supposed to be Giles?
Unfortunately for me, I respect this story very highly. I believe yours is one of the few that truly gets into the mindset of what Ripper might have been like and why Giles doesn't like himself in that phase.
I do, however, feel like it's a rather dangerous characterization to play around with because you're not leaving open to much reason for redemption. And Eyghon doesn't fit into this world of drugs, death and sex. It's too naive and too magical.
But this is a good story and well worth it just for your writing.
