I think I understand. To verify, you’re looking for reference materials (broad term, but it fits)Yes, but no single book to read or point people to - the best source at the moment remains the 3e FRCS. With the significant changes that WotC introduced in the Realms with 4e and then mostly reverted with 5e, this is, IMO, a notable omission (especially given that Ed is still around and even publishing regional setting books for the Realms, so they could just hire him as a consultant and/or contributor for such a book).
