Ellen Brock is an editor/blogger who offers very practical writing advice. This is the first in a series of three videos about world building. I've just gone through the process of creating my own world building bible, and I agree with her tips 100%. While world building is associated with fantasy and science fiction, I also include period pieces in that category. I realize that period pieces are more 'world recreation' but, the process asks a lot of the same questions that comes up in world building so can share the same benefits from a world building bible. Godspeed!
