Out of curiosity, how exactly darkness affect someone's ability to successfully navigate the wilderness?
I had just finished that custom move and I was going to reveal it when ya'll entered the rainforest xD
Oh well, I might as well address it now. So as you noticed, the darkness track is tied to your emotions (Anger, Fear, Shame, Doubt). If you had more than three marked, than you're in a very... negative headspace, I guess? Which means you're not thinking clearly when you're trying to navigate an area. If you have no darkness mark, I imagine your mind is fairly clear and less plagued by negative thoughts.
