Love the designs! There's a definite lack of historical fiction/fantasy stories set in the Americas. (There's a lot of settings that need to be explored in the genre, but that's beside the point.)
Just out of curiosity, as someone who's working on his own debut historical fiction epic, how much research has/will go in to Codex Black, and what are some inspirations for the story (characters, tropes, scenes, plot arcs, etc) thus far?
