Chichen Itza when the stars are right most likely. The stone table for sure.

Very very little "hard objective" data... like, is this person a Whampire, or not?  Yeah, you can get that as objective data (and such data can be important (e.g. may have saved Ramirez's life)).

But don't discount the idea that you can still get a very great deal of very "good hard objective data" from a 'gaze!

Repeating elements of the Dresden Files include that the "facts" (the "hard data") don't always tell the whole story; and that "objectivity" is more often a fools' errand than not.

  I think the White Council relies (much!) too heavily on the results of a Soulgaze.  But I think calling them "worthless" is even further off-base.  They are the single most penetrating way to look into who a person is, down deep.  And AFAIK we see no signs that a 'gaze can be substantively defeated, or defended-against (other than refusing to engage).
 I seem to remember (unless I mis-remember?) that Warden SOP is to get at least 3 'gazes on someone who's on trial.  That right there would go a long way toward circumventing any DuMornes who would subvert the system that way (if I am misremembering, then clearly they should do it!):  if the Warden corps are so corrupt that 3 random individual Wardens can reliably be presumed to deliver any pre-determined testimony you want, then it's game-over and the Bad Guys have already won.

They only do a soul gaze when they think it necessary and they easily execute you without a trial if they are convinced enough you should die. Remember Molly's trial. Harry did a soul gaze but nobody else did and if it was left to the merlin she would have been executed without a trial which was clearly a waste of time and effort.

I am quite sure lots of warlocks are executed without trial or soul gaze, that is the impression I get. Partly because if they have any idea they will fight to the death anyway, partly because they are dangerous enough not to take the risk and partly because the wardens have serious manpower issues.

No doubt the council has an important task and we would be worse off without it but there are serious problems as well. The story would be too simple without them.

Apparently a lot as far as the White Council is concerned.. Let's not forget that a Warden is required to do a soul gaze on a defendant, then give testimony about what he or she saw in a trail that could cost the defendant his or her head.  Also the Merlin, in Proven Guilty told Harry that he, himself soul gazed the Korean Kid and that he was not redeemable, thus deserved the chop.

But that is double subjectivity. First there is the soul gaze itself and then there is the merlin communicating it. Maybe the Korean boy could have been saved.

Of course they are subjective. That does not meat it is false.

Corona. I have visited the office only four or five times since it began. It is only 16km from home so I usually take my bike. There is a bus connection but that does not save me time.

What?  That Mister is not a Malk but a kick ass vanilla tom cat?  What's wrong with that? Talk about heresy!

MSTR is fully cat and fully white god. That is the mystery of the holy duality. No room for a malk.

Fix was a mortal  until he chose.  And I didn't say Eb didn't gaze him. But the statement is ambiguous. I would also point out that Margaret had a baby with Raith. And just as obviously she didn't share that with Eb. If Butcher is to be believed she was under a death sentence from the Council and running.  Eb's knowledge would appear suspect.  Which isn't to say you are wrong.

According to the Demon that Harry deals with in the early books she was on her way to Hell.  But found redemption. She had a baby with Raith. She threw Thomas under the bus. And managed to find the time to find Malcolm, cuddle up, and make a baby all while on the run from both the Council and a curse. She had had broken the first law.  A women of many talents.

We got some facts about Margaret but the chronology is unclear and we might get a completely different spin later. We don’t know when she broke the first law and when the council discovered that, it could have been relatively late.

I don’t know about throwing Thomas under the bus. He was a white court vampire and taking him with her would have been disastrous. She probably did what she thought best for him.
