I was in the void, but forgot what I was supposed to do there. I looked at my quests and saw the words “Talk to kahdgar in malarian to set off for Chaz al;gar” so I went to Dalaran. Cannot find Khadgar ANYWHERE.
If I’m not mistaken, in this case you want to use the portal in the SW market square (next to where the old AH used to be back in Vanilla/Classic) to go to Dalaran, not the mage tower.
