For what I know and believe, the derplander and his party are supposingly representing us, the ingame players. Their experience and their life are more or less ours too. The exile from Uldah we suffered before Heavensward is the same as us as u can see in the cinematic trailer of Heavensward. Well, more the derplander in the cinematic. So far, ingame, I dont remember a single moment where we meet any of them. So I would come to one thing : Those we saw in the 3.1. cinematic trailer are definately dopplegangers. Somewhat representing us in the dark way. So what we can actually ask now would be : Who and where are the orginals ones and would we come to meet them ?
