I wonder how much gender played into the variety of powers we see in each individual ark, with Artemis’s descendants having fewer or at least less varied powers compared to Farouk’s.
Anima has its readers, menders, one and one former mirror visitor, and the general ability to animate inanimate objects. In contrast the Pole has a much wider range of powers that are all distinct from one another. Illusionists, chroniclers, invisibility, claws, whatever the Web can do—and that isn’t even all of them. Each ability is also far more distinct on the Pole whereas on Anima they seem to have mixed with each other to the point where you have common traits (animating) with the rest popping up more randomly across households.
My thinking here is Artemis would have had to carry each of her pregnancy to full term, meaning that the number of lines with distinct powers would directly depend on how many times she was willing to do that, and it's something that Farouk wouldn’t have had to contend with. I wonder if that’s also why we see Artemis exhibit traits her descendants seem to lack, such as her ability to manipulate matter as we see her do with her throne in her observatory (of course it could always be the case that that’s an advanced technique that only she’s able to perform). You could also chalk this up to being a result of their personalities and interests, since Artemis doesn’t appear to be interested in physical pleasures whereas Farouk’s court is built around them.
This also brings to mind why the Pole are so vehemently opposed to Thorn as a concept (aside from his general adherence to the law and screwing people over with it) I think part of the answer lies with him being a muddying, so to speak, of family lines, something that doesn't seem to be all that common on the Pole (which is hilarious when taken with Farouk’s proclivities). Family loyalties are meant to be absolute and Thorn stands in direct contradiction to that.
Of course you then have the Gift which brings this all into question, then again we see that the ceremony does work in increasing the potency of even the one shared power, and we never see any mixed-line couples so this point might be moot.
