As far as I know, the Speaker was there when the city began construction. That was centuries ago. So how the heck did he live so long?!? He is definitely not a light bearer. We’ve never seen him with a ghost and he never used his powers. Unless he’s exo, or awoken. Those are the only two races that live that long. Exo are immortal and I’m sure awoken just have a looooooooooong lif span. But we don’t know because we’ve never seen his face.
