Mu Nuan was born into a small family, having both parents as well as a signular sibling. They spent the majority of their younger years studying medicine with their mother and helping take care of the younger brother. They soon distanced themself from their family when they were a young adult, wanting to become a travel doctor to those in need. Her home was very traditional in the sense of looking down upon those who wander to leave. Her whole village had this mentality unfortunately.

With skill in medicine and overall health she was very well off being a travel doctor. They always had the intentions to bring wealth back home, but unfortunately due to the split opinion, this would not happen. They rarely would return home only having good relations with her younger brother. She carries a very kind personality, but can come off boring due to her lack of wishing to share stories. They only enjoy sharing information about themself once they have gained enough from the other in the conversation. Trust is extremely vitial to them, being as they travel alone, vulnerabilty to attacks and harm are very easy to come across.

Mu Nuan's abilites, besides her understanding of medicine, fall under the scent she produces. Muntjac deer have extremely strong scent glands located in their face, this plays into her ability. She creates numerous aromas with several different side effects, leading to even be hallucigentic. Naturally, they have a scent that relaxes those who intake it, leaving Mu Nuan to never come off as a threat to most.
