So I just finished the Cassandra "boost" hit level 66 and I searched on forums and it said to go to ashkeena and do quests, but I can't see any quests? Apparently there should be 3-4 quests that get me to 70 and then a questline that takes me to 90?

I've been grinding in Ashkeena for almost 8 hours now and barely about to hit 67, any help would be amazing!
