I have no idea if that barrier would also take away her existence from Zmerr or if he would still see her or what not, if the barrier creates some kind of pocket dimension that keeps them both in a separate place in space I know of something fun to add, a little reference to her hidden powers potential.

off course if you rather just reply to it in general feel free XD
but at least in any case I do want to know more about the workings of that barrier
