Sorry I couldn't resist xD

From what I remember, the events between 2.5 and 3.0 were only a matter of weeks. As far as the exact year, I don't think Fern has touched upon that yet. Time is tricky in MMOs because each quest has it's own timeline, as well as each player. Sometimes they overlap to a point where continuity doesn't necessarily make sense. Until we have an official word on exactly what year the events of 3.0 began, it's hard to determine how long the 2.0 story went on for.
