Well, the royal color is generally believed to be functionally immortal unless killed, and if Her Imperious Condescension was going to abdicate, she'd have done it by now. She doesn't suffer her potential heirs to survive long enough for two or more of them to join forces, either. Lifetide's been smart and very lucky - she'd need to be, to live long enough to take an adult name - but she won't be able to evade her ancestor's enforcers indefinitely.
