Hi there, Acidfaucet, just a few questions concerning your post:
Which duke were you contacting? I'm assuming you have done evocations before, from goetia and other grimoires, and I find no reference's to any banishings after the working. You say you wanted to use no protections, Why? out of interest.
This is just my opinion, but again why give a "blood sacrifice" even though you say it was figurative. My understanding of the astral is there are no "figuratives". Would you use "protection/banishings" if you were evocating to the physical plane? Again my opinion, I view the astral has(very simply) walking through a zoo, which has no fences/cages around the animals. You don't know what you'll bump into.
Your working and prep, appears to have worked well, and you contacted the entity needed, so you must be congratulated in that respect. And I'm assuming again what you asked for form the spirit, you recieved. (IMG:
