Strictly speaking, Eldest Princess was not a form of address, but a title.
Take the Third Prince, for example. He had been the Third Prince since birth, and as long as he did not rebel and fail, he would most likely be called the Third Prince for the rest of his life.
The Eldest Princess was different. This title had to be conferred by the monarch. Without that investiture, even the eldest legitimate daughter could not be called the Eldest Princess. And when a monarch conferred that title, it generally meant only one thing-she would become empress in the future.
"So, will this Eldest Princess become empress?"
Elliot had asked the Old Butler this very question not long ago.
Conrad was already Elliot's confidant, but his aged face still twitched at the question.
"Absolutely not, young master. You would be better off supporting the Third Prince than her... no, please pretend I never said that." The Old Butler had clearly been so upset by the question that he had made a rare slip of the tongue.
Seeing Elliot's noncommittal expression, he hurried to warn him, "Young master, Victoria's status is extremely unusual. You would do best to keep your distance from her."
"Oh? How unusual?"
Elliot had meant that as a question, but the Old Butler clearly misunderstood him. He merely shook his head and sighed.
This made Elliot somewhat suspicious. Had the original owner of this body been very close to Victoria?
Thinking about it, that was possible. He had specifically asked, after all: he was the only member of the Sterling Family with a library card. Even the Old Duke did not have one.
But... judging by how tight-lipped Conrad was, could there be more to it?
Surely she had not taken part in that Frostmoon Uprising too?
