Debauchery

Praise The Blood God
"You seek death and I would gladly rend and tear your soul. I would rip your
flesh screaming from your bones and garland this body with your entrails,
but your death is to be far worse than even one such as I could devise. Your
skull will be honoured with a place in one of the bone mountains within
sight of the Blood God."
[The Omphalus Daemonium in Graham McNeill's Dead Sky, Black Sun in the Ultramarines, Omnibus p. 533]
Obliterating
Earthshaking
Desintegrating
Terminating
Blade, saw, needle and flame
Killing in the Blood God's name
