At the moment it is appropriate the Queen has a Council system (it's similar to what Queen Elizabeth Tudor had) but political systems evolve and I wouldn't rule out changes here, especially if the Queen continues to act in a way likely to cause continued and sustained criticism. L'Evallier, her Chief Elf and Council Leader, is outspoken in his comments to his monarch at times but she is aware she needs that criticism, which generally is a good thing. The Queen is understandably concerned about her realm's security given it has faced attacks from other worlds in the past and there is the ongoing battles with those who use magic for evil within her own realm. This dual jeopardy adds to the need for a broadly unified government (as we in the UK experienced during World War 2 in particular). I like historical echoes, not just in my work, but in other authors' short stories and novels. I think these echoes give depth and help "anchor" the invented world so as a reader I'm thinking, yes I could see that happening.
There is a basic broadcasting system and some press activity but nothing like the grand inquisitors of journalism who hold politicians to account. It's fair to say Roherum is not the most in depth journalist there has ever been.
True but because of that Roherum gets more interviews from Council members (and even occasionally comments from the Queen) that a more abrasive approach would be inclined to switch off. Not that Roherum's great rival, the weatherman, can see that. Roherum can also come up with the odd in depth question but it's usually as a result of him following a train of thought all the way along the tracks rather than just leaving it on a platform somewhere! It nearly always surprises people when he does do this and, again, it tends to surprise honest replies out of people.
