Alas - in this world, at least, my aether is far too limited to create anything much larger than furniture. Something like this- well, even outside of all that I've just described, it's almost certain that the material is of some nature beyond the mundane, that it functions as a whole with the barrier above, and to Create of that material would take a great deal of research. Research that I have my doubts our hosts would allow me to conduct upon it, assuming it not to be merely divine blessing.

[He says it with no small amount of disappointment. He does so very much miss the ability to simply create, without having to so carefully measure his strength.]

Even at the height of my power, to Create the entire span of the wall would be beyond me. A space such as this gap would be about the limit of what I could manage from scratch, and would leave me able to do little but recover for some days. Easier to create a framework and then fill it out, much as they do in mundane construction. Far easier, perhaps, depending on the level of detail involved; a wall is nothing so complex, but something such as the temples would be far too much detail for even one such as I to hold in the mind at once.
