I have recently started working with Sallos, of whom I have felt the presence of
For around two weeks prior to this, I was working with Dantalion - I promised him rewards upon fulfilling my request, however in a fit of anger, I wiped away his sigil from the mirror I was utilising, that I had sealed with my blood, and soon after began working with Sallos, promising him the same thing
My question is this - Will my request to Sallos be ignored, as I have previously asked Dantalion the same thing, with the same reward, or did dispelling the sigil cut our deal?
It is possible your request to Sallos could be ignored, yes.
Acting as you did with Dantalion was a breaking of your agreement with him in a fit of pique, and spirits don’t generally take that lightly. If you behave that way every time things don’t go your way, or don’t happen fast enough for your liking, no spirit will want to work with you, as word gets around, and the worst reputation you can have is as an oath-breaker.
My advice would be to contact Dantalion, and apologise. Let him know you value his help and that you acted irrationally. He will understand.
