Sure!
Hmmmm. Should we think of these as magic items along the lines of the infamous apparatus (of the crab/Kwalish)? Well, let's proceed maybe along the lines of the servants of Phlegamor --- mindless constructs that use the mental stats of their "drivers."
I'll have to read the information you sent. I get the feeling these are going to be quite complicated.
Whew, these are complicated. We have our work cut out for us! First question, I guess, and I'm of two minds: template or some weird kind of construct? Or magic item?
I think I'd take that approach as well. And I'd put in construction requirements for the actual construct part, with create guardian as sort of a special final requirement.
Anyway, which one first? The wooden one?
