The princess's mother is from a race where remembering each other is very important to survival. If they are forgotten they die. In the case of her mother, if you give birth with someone not of the same race, you die and are completely forgotten. So when the princess was born the mother died and everyone forgot about her and the fact that she gave birth, therefore forgetting about the princess

Her mom didn't die immediately so she very well remembers what her mother said to her, so she must have been cared for 2 a certain point. But for the most part it seems like she survived on her own with the help of animals and the spirirt friend that comes in the winter whose taught her kost of what she knoes. She resided in the rundown storage castle so she probably found things there as well to live off of.
"I don't know her id"
"Then just write yours"
That was just pure butter I'm taking notes
