You know what, I thought about doing the lost male gerudo thing as Din's child. I mean it's been long enough right? He'd be snatched up by the yiga not too long after he was born because they think he's gonna be reincarnated Ganondorf. Then nothing happens so they cast him out and he becomes a wanderer? I feel like that fits in pretty well with the fact that one clearly isn't mentioned in BotW.

That said, I don't wanna detract from Crusader's idea though, so I'll come up with something else for now.
