This could be interesting, could your chosen god be someone like Cupid or Athena perhaps? Or Morpheus. Another option is Apollo God of Music.

All of those are certainly options.

What does the status of being a Communicator actually confer? What level of autonomy are communicators actually allowed?
[/quote]

Being a Communicator means being a God's personal soldier, in essence. They are the liaison between the God world and the Human world, responsible for communicating the message of said God and eliminating any existential threats to the human/God realms. 

They're like soldiers in respect of autonomy. When required to do a task, they must be sent out to complete it soon, but when off-duty, they're given free roam across the entirety of Avalon, which is in essence a mythical paradise. They're also allowed to visit home for a good amount of time per year, and all their needs are provided for.
