I am not going to comment on the actual objective, as I do not have anything of value to really add to it. All I will say is good luck and to be prepared for all possibilities.
What i do want to comment is the mentioning of Belial. Before I say this, I would like to note that I do work with Belial and it is from that working that this comes from. If he does accept and pull through with it, it will be a sign to keep a close eye on him. If he can override someone’s freedom, what is to stop him from turning the tables on you? While he is known to help others, he ultimately has his own agenda, as all spirits do. And one’s own well being is not always align with said agenda.
One of my core lessons with him is to always keep your eye on your agenda. To achieve them, it can be necessary to build bonds, as long as you are aware that there may be a time to flip the table on the loyalities when its necessary, regardless if we are talking spirits or people.
That does not mean it is not okay to be respectful and grateful to these spirits. But I have contributed in the mistake of failing to make that point aware in discussions about spirits.
