I chose Stormsong Valley on the Banshee’s Wail, unlocked Warfang Hold, received the Return to Zuldazar quest and turned it in to Nathaniel Blightcross.
Now I’m waiting for my first minion mission to finish and cannot find a single quest anywhere else.
Any tips?
Your primary questing hub is Zandalar and the three zones encompassed within-- Vol’dun, Nazmir, and Zuldazar. While there may be quests that pop up as you progress through the Alliance territories (Stormsong, Drustvar, and Tiragarde), they are far and few between and are primarily filler quests and war campaign as you progress through your levels.
You’ll mostly want to stick to Zandalar, and there should be breadcrumb quests offered in the Great Seal of Dazar’alor.
There is generally plenty to do, Face, but some things require you to unlock others. Definitely complete that mission.
You should also be able to quest in any of the three zones, Zuldazar, Nazmir and Vol’dun. It looks like you were questing in Vol’dun, and abandoned the quests. You can return and get Answering Their Attacks and Dressed for Battle and continue in that zone.
You’ll be able to select a different zone once you complete that one.
I should note, a Game Master will not be able to provide you any guidance outside of recommending that you visit sites like Wowhead for assistance.
