As most of you know, in Skyrim there is a Mysterious character who sends the player messages on where to discover their next word of power, but it is never revealed who he/she is, they are simply refered to as "A Friend". Who do you think it is that tells the player where to find the Word Walls that are found about Skyrim? I myself have a rather lengthy theory but I want to hear what you guys have to say.
