Fictional Material Manipulation is a good choice since the aether counts as fictional but material wise well with how it's said the gods breathed it I think it's a material of some kind but the reason I find this power to be incredibly unique is that you could in a way make a material composed of dreams that can grant perfect wishes or create the very metal that wolverines claws are made of. This power is so versatile.
Everyone got such an interest for fiction based powers, like I'm not talking about the plot powers category, the ones that mention fiction in the title.
