Inspired by my not-quite-ship from The Keepers by Jackie French Koller (Nell x Lord Taman, a would-be-but-not ship because while Nell reads more like an older teenager, she's supposed to be 11, so that would be sick), a kingdom (presumably in the Estagon universe) is the home of an elderly king, a middle-aged queen, and a single teenage princess. Though the royal couple desperately wanted more children, they were never able to conceive again, and so the only other member of the royal family is the king's late brother's son, an almost-thirty-year-old man who is expected to inherit the throne upon the king's death.

The gist, then, is thus: the princess's cousin made a deal with the Nox or their deity to secure the throne for himself. But when his teenage cousin, the only person who can possibly challenge his claim to the throne, becomes infatuated with him, he agrees to marry her and slowly begins to return her affection. Realizing now that he doesn't need the Nox to steal the throne from her, he attempts to back out of the deal... and it obviously doesn't go well for him.

I am also amused, meanwhile, by the idea of having something of a "thirty gambit pileup" involving those kinds of inheritance shenanigans. Pit a Roger, a Taman, and a Jafar against a king all at once, and what happens? Fun shit, I'd wager.
