The community always loved the mysterious and erratic Katrina. Her interactions were always interesting and her aesthetic was on point. Seeing her in the village square never failed to provide intrigue and suspense. People are also fans of her voice and chants.
Unfortunately, Katrina only comes every now and again and her mystical teachings are not always reliable, so it means that she does, unfortunately, end up towards the bottom of the list. Believe me, Katrina is one of the best in-game NPCs (not counting villagers for the sake of time and sanity) and it is a shame to have to put her so low.
