[That's kind of confusing but she shrugs it off. There are no schools or history lessons in the countryside, just tidbits that the elders and the travelling merchants say. She never paid too much attention since she never expected to meet a noblewoman like Yona. She could've sworn the name of the king was Yakshi and that he was Hiryuu's son or grandson, but apparently she was wrong. Her whole hometown was wrong, most likely.
That would explain why Kija had used "descendants" of the Dragons and not, say, children or grandchildren. Right?]
Oh, then I misunderstood. Sorry, like I said I don't know anything about royalty or history. Thanks for telling me before I messed up in front of Yona, Jae-Ha.
