How old are our characters supposed to be?

For your player characters, it has always been left to your own interpretation how much time had passed when they log in after the arrival of a major update or new expansion. Dragonflight is no exception. You are free to imagine what your characters have been doing in that time of respite as you look forward to the arrival of the Dragonflight pre-patch.
