The Captivating Princess
From The Fifth City Wiki

The Captivating Princess is the Queen's youngest child, and the only ahistorical member of the British royal family. She was born right after the Fall.
Unlike the rest of her family – who rarely stray far from the Shuttered Palace since their power and popularity has largely crumbled – the Captivating Princess is very much a social butterfly. She moves both in the most rarefied circles of high society and the most unsavory places in all of London. Her honey habit is common knowledge: she's even rumored to have her own honey-den in Veilgarden.
However, scandal only seems to enhance her mystique. She's renowned as an arresting beauty, and stays a most desirable guest at salons. She has never terrified anyone.
