Do you feel confident that the uninvited and the unknown one are who they claimed to be?
This sounds like a trap. Invoking is a form of mild possession, so I don’t know if I would want to invoke any entity inside my system that I had not previously evoked to build some kind of relationship and get a feel for how we get along first.
The one entity you wanted to call didn’t show up, and a bunch of others you didn’t invite did - that’s a red flag for parasites, but at least they didn’t just pretend to be Lucifuge.
How are your shields and wards and did you banish before you started?
