For those of you who perform Banishings, one Deity I must recommend is Lady Heckate.
Now this is because she won’t outright kill a Spirit, she will guide them or take them under her wing and in turn that Spirit may either cross over successfully or will join her legions, resulting in a strong mutual benefit.
Don’t get me wrong, she can kill a Spirit if necessary however she helps those who are lost and may not even realize that they’re harming you to cross over.
In return you may give her offerings. I generally play music to her as a way to honor her.
Agios O Heckate
