So 100 years before breath of the wild that mural that impa shows Link in botw there's a figure. That is confirmed as the same figure the ancient hero's aspect is based off of. This is 100 years before botw remember that. And aoc doesn’t exist because it’s a non canon game. The ancient hero’s aspect is a Zonai. But how is that possible because apparently Rauru and Mineru were the only Zonai left after that kind. So how could another be there. They can’t be the only ones left then, that wouldn’t be true. Because for the bloodline to continue they would have to have a child during the events of totk we didn't know about because they died as we saw. So there's another that continued the bloodline. But I have proof Zelda has Zonai blood in her veins as well as the blood of the goddess. Because when Sonia and Zelda first meet, sonia says that she sensed a BLOOD CONNECTION between her and Zelda.
But that's not final! So Zelda could be a direct descendant from Sonia's child's child and so on. HOWEVER! if Zelda was a descendant from Sonia, (and they have a blood connection - which they do apparently) then that means either Zelda's mother or father would be a descendant from her too. And who died before we knew anything about her? Zelda's mother. We’ve never seen her face. We’ve never been told anything about her. But Zelda’s father knew about the Zonai. Because he knew what was under the castle, according to Zelda. And what is? Zonai statues and murals. But wait for it. Here's the proof Zelda and maybe her mother and everyone before leading up to Sonia and Rauru (a Zonai)‘s children has/had Zonai blood in their veins...the Zonai were descendants from gods, weren’t they? Gods…or goddesses…? They could be direct descendants from Hylia, and the blood of the goddess was passed down through the generation all the way to Zelda. But what is Zelda’s title? What is she known by and has been known by this whole franchise? “The girl with the blood of the goddess.” And possibly now, after seeing the events of totk, she could have had Zonai blood in her veins all along too. Which is why the Zonai secret stone reacted to her powers when she picked it up. Because it senses that she is actually a Zonai.
