My last understanding of Crowley, the previous reincarnation of the fallen angel Satan, is that he's been overpowered and / or tricked by Dagon since his arrival on Earth and possibly even before on another world.
Now on 7th stage physico-mind control, he still manages to willfully vibe his original angelic vibrations.
His role in the first birth of HLDBA remains undetermined : either him or Bar Vader, is the biological father of HLDBA.
The individual called Dagon ( i personally call him Zazon ) seems to stay very close to him and Lady PKiss ( the Yuria's head / Ankares' original body Lady )
to work operational evil on me and the forces of Good .
Another information is that Yuria's own body has logically been attributed to someone else :
it's difficult to determine who has her own body. One possible guess amongst many would be :
Sarah Schwab ( Patrick Sebastien behind )
