...Esther doesn't remember her parents at all. To protect her, they smuggled her out of Albion, having switched her with a stillborn. Everyone thought the child died. So Esther spent her whole life practically on the other side of the inhabitable world.

...she didn't even know we were related until I accidentally let it slip. I'd only found out, myself, just ending up here. So having a sister is a very new thing for us both.

[Mary sighed.] But it was hard. My mother, at least. My father was just someone that had always been out of reach. I suppose you can see why I just don't talk about them. As far as I'm concerned, Esther is my only family.
