There is a very special and powerful ancient angel who is able to drive off enemies and those who would harm you, take from you, cheat you or treat you badly. This angel is not the same as other more widely known angels, he is specialised in what he does.
I am not going to mention his name here, but I will tell whoever buys a ritual who he is then they can link in to him if they so wish. This angel was called on for help in magickal workings 200 years ago and is still well able to help today.
