Teclis didn't actually defy Finubar to found the Colleges of Magic. He just didn't tell anyone on Ulthuan it was happening until after it did, and persuaded the two people with him that he was right, which was probably helped by the fact he was their friend.
There's an entire trilogy about Teclis and Tyrion's youth before Teclis goes to the Empire, and Teclis also features pretty heavily in one of the Gotrek and Felix novels.
I think this depends on your reading of the situation at this point. Personally, given that the Eonir referred to both their own and the dwarven waystone systems the as "a piece of the network" rather than separate networks entirely I think it would, in fact, be valid to liken Mathilde to a plumber.
Yes, it would provoke an attack, that's why it takes political will to stick an army there for and end result that's going to be a bunch of unimproved no infrastructure farmland. The empire fought beastmen before they had the colleges of magic around, magic is very useful for fighting them but is not in fact actually necessary.
The mechanism by which tainted locations are cleansed isn't prayer, it's fire. There are explicit mechanics for making it go away with fire, and no equivalent prayers. The only spell that assists in geomantic cleansing is the Jade Spell to cure blights, which only works on natural sicknesses and a particular spell in the Lore of Nagash used by Nechrarch vampires.
It actually killed 3/4ths or 9/10ths, depending on source. (One source said it killed 9/10ths and crippled half of the remainder!)
Our Wagh destroying mountain of doom was pretty good. It was a problem that our magic, in specific, was well suited to deal with , and we had thus an outsized role in preventing it. But I would object to the characterization that having a high level magister on staff is reliably better than, say, having so much wealth you can hire tens of thousands of mercenaries on command and support your kingdom with hundreds of artillery tubes, when split across the sum of potential military solutions. Or definitely better than making friends with all the surrounding countries, so that the one being hit by a Waagh like this isn't you. And so on, even if we ignore that a merchant could hire wizards, or a diplomat befriend them, etc.It does take a lot of administrating to equal a WAGH destroying mountain of shadowy doom though
I really object to equating priests and magic in this scenario. Priests are not an inborn trait like magic is, and the specific question is... what could we do as a character if we didn't have the magic trait. Even if every person who used the winds left a kingdom, that wouldn't stop them from being able to have Morrites put the dead to rest, or Sigmarites to heal, etc. And you absolutely could solve Sylvania without magicians; when we did it, we used artillery and mundane armies to do the heavy lifting.
I checked the wiki, but it only said less than half the previous generation.
I can't see how much more explicit it gets than having a nifty chart for its precise application. This isn't something I've invented, or that only works on small things; it can deal with taint all the way to the same corruption level as the Marcher Fortress.
I checked the wiki. Lore is whatever you want it to be.
Being in the area of Qrech's old Combe is a unique opportunity that will not come again.
That's not far from the span we have IRL for how many died to the black death, and that's both more recent, and we don't have with constant supernatural evil buggers.
Explaining how we learned that is not a conversation I want to have.
