This process and the ensuing chat with him led to me being given a sigil whic could be used to call him. I was told to place this image on a candle to invoke his presence, and thus I am sharing this with you:
I've experimented with his energy a fair bit, and in so doing I've found that he can be easily used to better and advance an existing relationship. I would not recommend calling him to create one anew, as that is clearly not his role.
Enjoy!
