Funyn I was reading the last comment when Wyll spoke to me about his reputation and dragons, etc...
It's true I can't believe this guy can be this famous with THIS level xD
That's the point. Wyll talks on and on about what a great hero he is, but based on how much he talks about it my guess it is just that - talk. I highly doubt that a guy that his biggest nemesis is a lame goblin ever saw a dragon prior to the game events.
