(For some reason, the lore page is not loading.)
Jade was born presumably 18 years before the current year. (I could find literally nothing relating to what year it is.)
At the age of 7, their family and home was destroyed by those they can't remember. Some think nobody died, and they were simply attempting to move before catastrophe struck. Jade saw enough to know better however.
After that age, they simply studied and grew. No vast adventures, not even very many friends. But at the age of 18, they finally were kicked out of their school and adoptive home, left to fend for themselves. No shelter, barely any clothes, and no food.
