I know there has been no definitive statement made, but imo, the devs have eluded to the year passing to be tied to expansions. Something they have already stated will be once a year. So to my thinking, and this is my own personal opinion mind you, Erik ages in real time. I started back in game during beta and he was 33, at his birthday (in August) on the day of the 2.0 launch, he became 34. On his up coming birthday, he will be 35. And so on until the game ends or I murder him.
