I never thought why so serious like this, she is just my OC ROTG but I'm intend to thinking her story more then my personal works XD.
She use to have English/French name and it's not really make sence to me so "Cynthia Lapine" is her international name. Her chinese name is "Yue Liang Tu" (Moon rabbit) right now.
After researching I was really enjoy to imagine how she would be in her golden age and probably more then thousand years because mid-autumn festival legend were begun in 202 BC (so Cynthia does't like talking about her age much)
Moon rabbit can make elixir of life for such as babies, a spouse, beauty, longevity, or for a good future to believers.
In real "Moon rabbit" folklore. The rabbit is a companion's Chang'e, the moon goddess of immortality. Jade rabbit was down to earth for rescue the villagers from illness. First appearance is wearing cloth, holding jade mortar and riding flying big cat for traveling from moon to earth. In present day, her appearance was changed to be a little ordinary jade rabbit.
In my version, she was a rabbit on earth but sacrificed MiM's life so he took her to the moon with him. Cynthia's duty is making elixir of life for save the believers (most of them are Chinese people) same as real moon rabbit folklore.
Sadly she had short golden age, no one believe rabbit in the moon anymore. Cynthia lost her weapon(mortar), her pet ,fighting ability and her luxurious cloth (nothing you can see, her body is full of fur - -' ) at last, Cynthia have one ability left, is a making elixir skill. In modern age, moon rabbit is still give an elixir of life, travel by flying boat, although no one believe in her.
I tried to draw her in Chinese ancient art (in her golden age).
First I called her "Guardian of moon" but sound looks like Mary Sue, and "Guardian of life" is still Mary Sue... but sounds most make sense >
Actually I wrote her profile here [link]
but my English is really poor XD.
Her albino tigress's name is Zuan Shi (means "Diamond")
