Tablets of the Earth

Some time ago,my brother Brann sent an urgent message from Ulduar. He said he'd found an ancient titan cache with mysterious and important relics. King Wrynn dispatched one of his fastest ships to Northrend to transport the courier and the boat should've arrived by now. I'm worried,<name>. I haven't heard anything about the courier's arrival. Would you be willing to travel to Stormwind Harbor and see if he's arrived?
