could a bard of void "invite the destruction of void" by asking questions, allowing them to be answered, but never answering them themselves? or would that be more a maid or sylph's job, "creating void" by asking more questions which nobody has asked before and pointing out holes in the group's understanding of things that people may not have noticed before?

Ooooh that’s actually a pretty interesting take on Destroying Void, yeah! I like that.
