The letter in his house, his own dialogue as servant and the dialogue of the woman/his wife? in his house suggest his name is Gajus.His wooden puppets show knowledge about the Cycle. Is there any more meaning to them? They seem like scenes from other peoples lifes in some cases.He talks about the Cycle and calls himself fleshless observer.He is in contact with someone as powerful and immortal as himself, through his letters. Who is this other person?The dialogue of the wife suggests that he is waiting for something, maybe an end to the Cycles, a world where they can live happily.He seems to know about your identity and could have told you directly how the Cleansing would happen, but chose not to. Maybe he has tried exactly that in the past and it didn't change anything. He even helps you along the path, by giving you the Word of the Dead.From his letter: "Pride was my downfall." What happened to him? What did he do? Was he a Prophet as well, that could only survive the Cleansing and saved only his wife, who is not immortal?One of the lead game developers said, he thought, the Aged Man's identity would be pretty obvious, if you listened to the dialogue, read his letter and looked at his wooden puppets.
