I have PMed you with some private notes, here's a few other things that everyone else would need to know:
1) Name, and katanas. Sorry, but this isn't a place where you have freedom to mix any cultures you want. I'm pretty flexible as long as you keep it European, but I won't bend beyond that. The name must change, the swords... as you described them as a straighter version, I'll let it slide, provided you don't use the word katana. I know I sound nitpicky like that, but that's where I'm going to stand. Physically describe them, if you must keep them the shape they already are.
2) I
think you already understand this, but a few things in your CS make me want to reiterate, not just for you, but for everyone: An Artificer needs a Magus to make any of their devices work. In the case of your character's father, he likely would have been assisted by a series of young student Magi who would leave him when they had worked their way up their social ladder. You mention him never having any talent as a Magi: this is not only a given, but a rule. If you are not related to a Magi, you would never have access to that knowledge. It would never be an option.
As I said, that last part isn't an issue with the CS, just something I want to reiterate often so I don't have someone making a "grows up in poverty but finds a book of magic in an old shop and rises through the ranks" character.
I hope everyone is reading the lore, but I
do understand there's quite a lot of it, and it would be easy to skate past a point and make that sort of mistake.
