You find the word Palladia from a hereditary and history record of Castello Family.
 Apparently, the "dynasty" of Castello family was not recorded until the "founder" of the dynasty introducing the a version of improvement for bookkeeping system used in accounting.
 You found Palladia name was mentioned at the last part of the book.
 The first entry of her name was when she was introduced by the family head at that time as the next-in-line for Castello family heir, and you can see her full name there: Lisandrine Palladia di Castello.
 That was the first and the last entry for her name of that family history book. It seems this book was made long before the Cataclysm struck.
 There are a lot of Castello family's history before that last part, but most of them seemed irrelevant to the Lady, until one late-middle part of the book which mentioned that the head of Castello family decided to take two orphan as his foster children. The reason was undisclosed, but some speculate it because he didn't have anyone (worthy) to succeed the family business.
 Those two children were described in that book as follows:
- one was a boy while other was a girl.
- they share similar name, but didn't look like twins.
- further, it was said that they did not even related by blood.
- their parentage were both unknown.
- the boy was said to be an excellent heir for the family, as well as the girl, if only she didn't have frail body and health.
- however, the boy was stated dead several years after the adoption, thus the girl, who later introduced as Lisandrine Palladia di Castello, became the heir of Castello Family.
- at the time when this book was made (and ended), these two children's age were about 15-16 years old.
