Yes, there are still some small elements that remind me of common Chosen One issues.
The key is to make sure your characters do something to earn their place in the story. Greatness can still be thrust upon them, as long as there’s a cost, ordeal or decision that puts a character on the path they’re on.
Here’s some “from the hip” brainstorming to expunge any hint of that Chosen One aroma.
Kaylin
“Born into power” has low key Chosen One issues. If you make her authority a burden, that’ll help. Or, she’s the youngest princess in a patriarchy. While close to the power of the court, Kaylin has no chance of wielding it. But she’s the only one in her family that sees the danger coming for their kingdom.
(Can’t be a Chosen One if nobody chooses you)
Eric
Instead of a legend about who will be King, what if it’s a dusty old rule for choosing a leader no one has thought of in ages but is still on the books? Example: The kingdom used to choose their monarch based on who the dragons would listen to. But no one can remember the last time the dragons could agree on a single ruler, leaving it up to the humans to muddle through with clumsy old democracy… until Eric. It’ll help if Eric does something that earns the dragons’ allegiance, especially if it’s an accident. Maybe he has always been an unusually talented whistler, which earned him a pint and a spare silver when times were rough. But one day he whistled to get a dragon’s attention and he became a king. (accidental heroes are by definition NOT Chosen Ones)
Catherine
Maybe the ring is more of a Genie In The Lamp kind of thing. You get one wish and you have to hold on to the ring if you want the wish maintained. The Emperor wished for the ability to bestow power on those most loyal to him. What will Catherine wish for? (the power she has is the power she asked for – NOT power chosen for her)
Christopher
While everyone else is pulling lightning from the sky and fiery infernos from their middle finger, Christopher’s manipulation of the elements is limited to making it kind of foggy. He’s worthless in a fight, but when things get tough, he turns out to have a knack for running away. When the siege is over, Christopher tearfully picks through the rubble of his home and finds the master hanging on to life. With no other option, the greatest master monk of the elements puts the legacy of his order in the hands of Christopher, their most hopeless postulant. (there’s the heroes we need, the heroes we deserve… and Christopher: the hero we have to settle for)
Hope something in there sparkles for you!
