Someone, usually a supporting main character but not always, is obscenely rich. How did they get that way? Simply put, because their mother's uncle-in-law invented hole punchers. Their great-grandfather invented spark plugs. Their grandmother wrote one of the most popular novels of all time. Their father invented Toaster Strudel. Basically, their (insert relative here) invented or created (insert amazingly widespread, popular, or useful object here). Not to be confused with the heir of royalty.

- In the Dragon Age universe, the noble houses in Orzammar derive their nobility from being descended from Paragons. In theory, these Paragons represent virtues that dwarves revere. In practice, though, a lot of Paragons were basically inventors who just happened to invent something useful, making their descendants a bunch of royalties heirs with extra attitude... at least, according to Varric in Dragon Age II.
"And every person there thinks he's better than you because his great-great-great grandfather made a water-clock or something."
- Word of God is that Rin of Fate/stay night is supported by the royalties from her family's patents. Notably, she's not actually rich, as most of it ends up going into her family's brand of magecraft, which is very expensive. This is apparently a constant problem for her family.

- Taken advantage of by Lorraine Williams, the former CEO of TSR, inc., the company that published Dungeons & Dragons. As one of the company's side projects, she devoted massive time and resources towards creating and promoting a Buck Rogers RPG, including sourcebooks and computer games, despite the fact that the market for such a game was just on the plus side of nil. Naturally, the owners of the Buck Rogers trademarks would receive royalties for each such supplement sold. However, it just so happened that Williams herself was the heiress to those properties, which is just about as conflict-y as conflicts of interests get.
