So my partner and I were looking at the hero's aspect and for a while, we thought that maybe this was possibly this game's version of a Twili. Similar to a Zonai but not quite the same. Then, we got to looking at the colors and the headpiece and thought of how similar it looked to Ganondorf's design.

A running theory I have is that the Zonai that were imprisoned ended up becoming the Twili later down the line. A dang, Ganondorf is pretty miffed at Rauru for a lot of things, things he doesn't quite explain in game yet. Ganondorf also knows A LOT about the secret stones, like, enough to know that swallowing it will turn someone into a fucking dragon, information that I'm sure his HIGHLY guarded; it's a taboo subject after all. So How does he know this?
