Demons summoned according to the rituals and rules outlined in the Goetia will help you if you ask for their help. There are a structure and hierarchy of the demons in the Goetia. There are Kings, beneath them are Dukes, Princes, and so on.

The Goetic Demons can help with many things, some things good, some things nefarious, and some things are neither. 

I can give you love reading with the help of demons and advice on what to do.  

I will answer all your questions and tell you what to do.
