At least the levitating books should be not bound.
I say it is pretty similar to jewelcrafting. You need Summerset for it, but you can sell what you can craft.
Maybe the globes and furniture are to specific to the Psijics to have them to outsiders, but the books could be an exception.
WAIT WAIT WAIT. I can get psijic plans from achievements ?>!??!??!
Yup, was disappointed by this as well.
I understand that recipes are bound like any other Achivement items you buy. However, I think it would make sense to allow the items made out of those recipes marketable. We are taking about (cool) lights and chairs, not a unique item that someone who did not complete the question should not have in their house (eg: the Augur&co).
Hope they will allow this
