I'd also like to voice a similar concern as Lord Zee.

As [@A Lowly Wretch], Iva's Civilization should currently be the most advanced. And they have nothing like what this light god has because of the primitive state of the world. They do have a rudimentary government, fishing, boats, and an ability to build traps, hunt with relative ease, and make simple tools and structures.

Mortals shouldn't be making any large multi-story structures yet because that knowledge has yet to exist outside of Iva's Library and he wouldn't give it out freely.

Just my two cents though.
