Research and more research
I've begun compiling research on different mythological characters. I'm getting down a basis of their story of who they are and I'll go through amd make them more child friendly (since many have some things that a child doesn't need to know yet).
I want to reach out to you guys and see what your favorite time era to learn about was and if there is anything specific about it. For me, it's Ancient Egypt. I love the pharoahs, the gods, the hieroglyphics, and the technology.
