I have only read the trilogy of Vanyel, so I don't know about later time ò.ò but Vanyel *specifically* said (I can find the quote, I have enlightned it in my kindle) that the Vrondi would advise the nearest Herald of mages. Also, there is a moment in which he thinks that a passing mage had been made definitively crazy by the Vrondi.
Van describes it as "somebody tapping insistently on your shoulders, every few minutes" and I know I would hate that ò.ò
Now, peraphs the Vrondi-net changes with time, but I am pretty sure of what it was back then °-°

There are a lot of things I don't understand!
Are Herald-Mage particularly stupid and/or the Karsite particularly good to kill so many of them?
Why couldn't Heralds send mage-gifted youngsters out of Valdemar for training and then take them back to rebuild Herald-Mages?
What about people like Tallo/Moon?

Is it my ignorance or there are rather big plotholes? ç_ç

(Better for me, more to fill :P)
