Dudes, I was just imagining stuff and somehow ended up with an awesome storyline for a campaign which explains why there are no Barrow Deeps or furbolgs that were in them in WoW! It explains very much including why is there only one uncorrupted furbolg tribe on Kalimdor right now, why arent there polar furbolgs in Dragonblight, why did Barrow Deeps disappear, where does corruption of Northern Kalimdor really come from, why pandaren have completely disappeared from Azeroth in the last years and much, much more.
