I have heard, when it comes to incubi/succubi, that lower ones will submit to the big entities like Lilith but others won’t. Malignant spirits that are out there randomly doing harm aren’t doing it on behalf of Satan or anyone else, unlike what movies and religion say. A lot are just doing their own thing and can be combated with other entities that are helping you. I have found a wiki set up by someone who has a succubus and he said she told him there are specific ranks of their kind. I’ll look it up… okay I can’t access it on the work server, maybe I can link it.
As for average demons I don’t know. It would be really interesting if a bunch of magicians could intuit or get answers, and if they all match up we can have an agreed upon infernal ranking, which is just interesting for education purposes. I would say that outside of demonic organizations, where they choose to work together, there are just lower ones that will submit and ones that are lone operatives and don’t care.
