I want to continue pushing my ‘Magnus Quinn wasn’t actually a terrible swordfighter’ agenda.
Obviously, he wasn’t on the same level as professional duelists Babs or Pro, or soldiers Marta or Jean. He was a guy who did some kind of fencing in high school and then picked it up again in his 30s, presumably with some degree of seriousness.
When Gideon joins the other cavaliers in the training room, Magnus and Jean are sparring. He jokes about how badly Jean is beating him, but he must have some degree of competence for aspiring soldier Jean to find him worth training with. Babs then mocks him for getting beaten by a teenager and Magnus jokes, describes himself as “absolutely no good”, and praises Jean’s abilities…before giving Babs such a death glare he gets obviously embarrassed.
It’s worth bearing in mind that there’s some degree of tension between the Third and the Fifth. Babs will have know Magnus since he was small and has almost certainly seen him fight before. But the Fifth, their relationship, and the relative freedom that Magnus has to not be a perfect fighter (because his necromancer values him as a human being) is clearly something that rankles the Third. In TUG, when Ianthe talks about Babs, she explicitly references Abigail and Magnus. And what’s interesting is that she makes a comparison not just between Abigail’s husband-with-a-sword and her perfect tool to be moulded and used, but also to Corona’s aspirations to swordcraft:
IANTHE (Playing a card) She’s not here, so let me be fully honest, Sextus: my sister is not a swordswoman. She loves to wear big boots and wave a sword around, and she looks wonderful doing it, but her actual competence … well, put it this way: she’d lose to Magnus Quinn.
PALAMEDES Magnus Quinn was a cavalier primary.
IANTHE No, I mean Magnus Quinn now.
There’s…a lot…to unpack here: the comparison of Corona to the husband-cavalier is intriguing in and of itself on a psychosexual level, as is the contradiction between Ianthe and Corona’s own versions of Corona’s competence. But Palamedes’ response is also interesting, suggesting that Magnus was up to an acceptable standard for a cavalier, which Ianthe’s joking response seems to back up.
So Babs’ rudeness towards Magnus and Jean may have a lot to do with the internal dynamics of his own necromancer-cavalier relationship and not necessarily be an accurate reflection of Magnus’ abilities.
Likewise, Judith’s comment in the Cohort Intelligence Files that the Fifth is 'undoubtedly chagrined" to have “schoolboy fighter” Magnus representing them had to be read against the fact that we know from the Sermon on Necromancers and Cavaliers by Second House stooge M. Bias that the Cohort has a very low opinion of unranked “social cavaliers”. And Judith Deuteros may have her own reasons for being disdainful of a cavalier who is so…cavalier…about his intimate relationship with his adept.
Magnus’ own self-deprecating comment on his ability is:
“I didn’t get to be cavalier primary due to being the best with a rapier. I’m cavalier primary only because my adept is also my wife. I suppose you could say that I—ha, ha—cavalier primarried!”
But again, there’s a difference between becoming cavalier primary because you’re the best sword fighter and getting up to a vaguely competent level once you’ve become cavalier primary (guys in their 30s with high powered jobs tend to be scarily into their hobbies…) He is definitely the worst cavalier there (or would be, if Pro were actually alive), but on a general standard he probably isn’t as terrible as people like to joke.
Another important bit of context here is that all of his comments about his own ability occur in the context of Corona trying to get him to fight Gideon. The shy, silent 18 year old from the cult planet whose practice of cavaliership is generally acknowledged to mostly consist of carrying buckets of bones.
She gets paired with Magnus because they assume she’s not going to be much of a fighter and Magnus - neither a professional duelist nor a soldier - would therefore be the fairest opponent. Magnus is clearly uncomfortable. And Gideon is certainly Intimidating. But when you consider that most of his previous interactions with her have been trying to coax her out of her shell and clearly feeling rather sorry for her, his comments take on a bit of a different tone.
Does Magnus worry Corona has dragged along this poor kid out of interest or curiosity, and that she’s going to be humiliated and never want to interact with them again? As Corona says “Come—Gideon the Ninth, right?—why don’t you try Sir Magnus instead? Don’t believe him when he says he’s rubbish. The Fifth House is meant to turn out very fine cavaliers,” Magnus is politely dissembling, telling exactly the sort of jokes that would appeal to a teenager.
As everyone else mocks or is intrigued by Gideon’s knuckle-knives, Magnus is trying to look her in the eye through her sunglasses, bewildered that she doesn’t know to take off her robes or glasses to fight and then…suddenly realising that she is dead serious and perhaps he has dramatically underestimated her.
After his defeat, we hear him saying to Jean “I’m not quite that out of form, am I?”. Gideon’s abilities were totally unexpected: she severely tests a top duelist like Babs, and Magnus is surprised to be beaten in three moves. That suggests he’s been holding his own rather more comprehensively in previous sparring.
And while he certainly wasn’t up to Gideon’s standard, he may have managed to draw his sword before Cytherea took him out…
