*sigh*, since there's no more canonical material to build on, I'm just going to say that the Horrors started ever since Farsight met that blue-eyed dragon who was Fierceteeth's father and watched him die and had Fierceteeth, and then there was Mastermind, and Starflight was taken from Farsight and then the mommy issues started, then Farsight died on the continent, and then that volcano erupts and takes Starflight's eyes and a bunch of misadventures later, Fierceteeth somehow *isn't* a prisoner, has three children with Strongwings, and Starflight and Fatespeaker find love with each other and then out comes Destiny, doomed by the narrative. (and with the same profession as her grandmother, with whom the Horrors started). Maybe Destiny will somehow end the Horrors, because it'd be very sad to watch it go on.
