Lost Queen, have there ever been any cases of Yoldahr wyverns acting civil enough to breed with a Kuros dragon of either gender from both parents? And what was usually the fate of the offspring?

Lost Queen : Not that I know of, they’ve acted pretty aggressive towards us. They don’t try to kill us, but they’re not friendly. They’re stubborn, smart beasts that prefer to live their own primitive ways. I’ve only heard made up stories about those kinds of hybrids, nothing’s ever been proven to my knowledge.
