Honestly I made this mod for personal use as I was annoyed with the sect secretary being called JUNIOR (F). But since the result was good, I decided to share.
I decided to call her White Moon, in Chinese, Bai Yue, but the code is super simple to change and there are pictures in the description for anyone to put the name they want. The same process is used to change other NPC names.
Super simple mod, open source and easily moddable.
