In order to progress in this chain, you need to head back to your Shrine in the Vale. If you're Horde, look for Sunwalker Dezco and pick up Meet the Scout. If you're Alliance, look for Lyalia and pick up the same quest. Head to Krasarang Wilds and complete the chain of quests that follows, all the way up until your respective faction's base is established. Then return to Wrathion."
