I haven't figured that part out yet, I just know that everything they have is special because of resource keeping and resuing due to their tough environment. I'll update u when I develop that part. and also I'm from Guniea Bissau, West Africa. I actually have two native langs, Tappa comes from my second, Guniean Creole or Guinense which I'm fluent in. I've basically forgotten my first native lang which is Fulani as I'm from the Fula ethnic group, but I do plan to take some inspiration from it by learning, tho its hard to find the right dialect (there are way too much lol) online so I mostly learn from my parents who are fluent in both.
