The the last mage dies and magic is now truly gone.
If that's the case, all is good.
IME it very likely wouldn't be the case, however, as at least one player - be it the one who just lost the first "last mage" or another seeking to switch characters to fill the gap - would try to bring in another mage.
Not if all the other player characters have similar unique things and burning drives. The group will work that out, and there's totally room for other players to be supporting cast if they want to anyhow.
If they want to be the supporting cast, all is good; and some players are cool with this. Others, though, aren't.
It is not the stated premise of the game, it is the proposed, and therefore suggested and tentative, premise of the game, which is open to twists and even outright rejection.
If a GM comes to me and says "Here's the idea I've got, it'll be a no-magic game, you in?", to me that's a binary yes-no question: I'm either in under that premise or I'm out. Why? Because clearly that premise is what the GM wants to run with this time, otherwise she wouldn't have suggested it; and with a strong implication of that's what the GM thinks (at the moment) she's most likely to enjoy. And the GM's enjoyment is rather vital, as the game don't run without its GM and if the GM isn't enjoying running the game it tends to drag the whole thing down.
No, there will be discussion to come to mutual agreement about what everyone will find enjoyable. It's not like the GM has already written (or purchased) hundreds of pages of adventure material. Burning Wheel is not that kind of game.
The GM may, however, have already put a fair amount of thought into the setting and how a lack of magic would affect said setting (and system as well).
Again, it sounds to me like people have been taking "GM's proposed ideas" as "firm autocratic decisions to be accepted meekly" rather than as "laying out a beginning for a conversation".
If the GM doesn't want to run the game then there's no game. Here, she's proposing a no-magic game and the first thing she gets in response is "I want to play a mage". How is that not throwing her concept back in her face? How is that not asking her to run something she's just said she doesn't want to run?
Gollum would be amazing player-character material. He has his own drives, huge challenges to overcome, and in-game conflict is, well, the point of that game!
So BW leans into PvP? That's refreshing, at least.
Any other time I bring up PvP as being a sometimes-fun way to play people brandish holy symbols at me like I'm some sort of undead.
It was supposed to be a no-magic setting, for whom?
The GM, who's the one designing said setting as far as needs be done.
Clearly the table's interests have wandered from the initial suggested, tentative, open-to-discussion proposal.
To the point where they're likely to be seeking a new GM soon, I'd think; unless the GM is really flexible in what she's ready-willing-able to run.
