Enchantments
As stubborn as Elder Achak was, even he couldn't say much after Jin Wang showed them the remains of the other demons. And after asking around for a few minutes each and every one of these nine individuals could be traced back to whichever group they came with.
Everyone had the same things to say, that something terrible happened to them where they either lost a loved one or went through something horrible. After that they fell sick for a few hours and refused to talk to anyone, keeping their distance from the rest.
There was a very strong odor of sweat and urine following them wherever they went. Near the end they started to smell like rotten meat and most people assumed they had just died of natural causes.
Nothing particularly stood out about them. Different ages, backgrounds, personalities, and gender.
