I stated what i wanted and i tried to call on him to sign it but nothing happened? Should i look for little impressions or do they leave prominent signs on the paper
Spirits are not physical. They are not going to leave anything on the paper. If you have the sight, they might give a signature of sorts that you can trade over physically, but don’t expect to see it suddenly appear on the paper.
Would they leave like an astral impression
Yes, that is what I meant by the spirit leaving a signature you can trace over, if you have the sight to see it. Can you see and hear spirits? Do you know if Sitri even accepted the terms of the pact?
