As I was researching traditional Chinese medicine (TCM), I stumbled across the idea of a person having five souls. I think that's pretty interesting, in and of itself. But for world building, fantasy writing, and magic-system-making, it's pure gold.
Here are a few articles that touch on the idea:
Here’s one from The European Journal of Oriental Medicine: http://www.ejom.co.uk/vol-1-no-1/featured-article/the-psyche-in-chinese-medicine.html
From ThoughtCo: https://www.thoughtco.com/introduction-to-the-five-shen-3183169
