It's kind of hilarious how many Ls House Tachonis (and Primus specifically) have taken just because Julien is himself. Primus pissed off the exact kind of reckless but driven person that would swear revenge against the sorcerer that ripped his father's skull out of his head and mean it and fully throw himself into it, but also didn't have enough regard for him to kill him at the Palazzo Davinos even though he fully could have. Result: Two of his sons are dead, killed by specifically Julien because he has decided that House Tachonis shall join House Davinos. They also very much don't have the soul of Thjazi Fang despite giving him the scar because Julien is the kind of asshole who would spit on a corpse at a wake, evoking the exact kind of magic that is known to circumvent the scar. Result: Julien Davinos, to his own dismay, saved the soul of his hated enemy.
Primus is already livid at the fact that not killing Julien resulted in him being able to sneak into Obramus Manor and kill Koral, so he's surely going to be thrilled to learn that the same man is the reason he doesn't have Thjazi Fang is because that same man was a disrespectful asshole to the dead.
