He / Him
I would, again, argue that both of these are magic themed, even if they are not necessarily magical.Tinker certainly isn't, as clockworks are real things with no magic.
The Lore feature may be, but it seems more like an awareness than a use of magic.
This thread, as far as I can tell, is about finding a unifying theme for gnomes. If creating an animated clockwork device and identifying magic aren't magic themed, then you are using a very different definition of magic than I am.
