Few question about entites for writing

Hi everyone i want to start writing fantasy fiction and i have few questions.
Which demon or non demonic entity can help me with unique and creative ideas? Im thinking about Belphegor.
Which entity should i contact for helping me to improve my writing abilities faster?
And which one for selling my books?

Mammy’aon from the Book of Azazel. He’s a sort of demonic muse.

King Paimon, master of all arts and sciences.


Thanks. I really like this entity. I mean King Paimon.
