My suggestion, have it discover there can only be so many dragons of a particular size (age category equivalent). Something about a limit to the total amount of dragon energy*. To grow more powerful someone higher up the pyramid must die. That particular dragon doesn't technically have to kill them, but it makes it far likelier that they'll be the ones to grow. And of course they can't wait around for an older dragon to kick it.
Suddenly lots of humans and demihumans start learning the location and weaknesses of older dragons. They could even frame older dragons for attacks on settlements, causing adventurers to hunt them down. Bonus points if you can give some clues that it's them pulling the strings.
* Kayne West or Donald Trump could explain this concept better than I, ask them.
