when he was alive, he was severely disfigured from a tumor growing out of his head (another Sarnie told me this). I'm not sure about the tumor, but he was severely disfigured. he's the only son of a top high official. so he's rich and his household has a lot of slaves. he pretty much demeans almost everyone but his dad... always calling them "prai" (low class? i think). maybe it was a self protection thing being rude and demeaning everyone.
one day he asks his dad for a specific woman slave to serve him. he never shows his face to her until one day he went to some kind of festival to watch her there from afar. a fight starts among the people, and mart's veil falls off him while he was trying to save the girl. people started calling him "na pee" (ghost face i think). he gets upset, says something rude "prai," and they start hitting him. the girl pleads with them to stop, since they're at the wat or something. mart runs away, and she goes after him. she sincerely doesn't care about his appearance.
mart seems to fall in love with her, but she already has a boyfriend who she loves. so he rapes, beats & traps the girl. eventually, he kills her out of anger.
following that, he proceeds to take on many young slave girls as wives. those who opposed him would get beaten.
