That sorta makes it sound like the heir has to find the player so that the player can find the heir and shut the gates of oblivion... kinda odd[/quote]
I don't think we should take the trailer and what was shown in it too seriously. After all, it was just a trailer. A lot of the twists there were just to add to the coolness factor of the game.
So I'm pretty sure it's the player who will be running all over Cyrodiil, looking for the Heir who doesn't even know he's the Heir.
