Yes, I am speculating Neurovore just as you do frequently, but what I am stating is logical. Some of your theories are highly unlikely.
Perhaps. but they have their own logic.
Sorry, I do strongly disagree with you about positions having limitations such as the Blackstaff which is someone that can violate the Law. I will cite examples in real life such as the position of the King's Hand. It was someone who could carry out almost anything to take care of threats to the King or Kingdom. He would do things that the King could not officially acknowledge such as threats and assignations or spying, bribing etc. There are secret agents like the fictional James Bond that had a license to kill. They could violate all sorts of laws such as travel to sovereign nations and spy and assassinate enemies and are granted much leeway and latitude. Yet if these people went rouge or did things too off the wall or turned traitor they were removed from office, arrested or more likely killed.
I don't see the relevance of your real-life example. You might as well compare the position of Blackstaff with the swords in China - Manchu dynasty I think - given to people as an honour that meant they were entirely outside the law - and following which it was then perfectly legal for them to go as off the wall as they liked.
I feel my theory that there are some unknown checks and balances is a more likely theory than your theory that there are NONE. Would you care to prove your theory?
If it were provable, it would not be a theory; theories are only disprovable, and I still feel that a Blackstaff with checks and balances is right back in the position of a wizard who has to obey the laws; any constraint at all can be hacked to work against the person constrained if the enemy is smart and ruthless enough.
