Description
Some time ago, sent  an urgent message from Ulduar. He said he'd found an ancient titan cache with mysterious and important relics. dispatched one of his fastest ships to Northrend to transport the courier. I was to meet him here and examine the tablets, but the courier is nowhere to be seen.

Magni is worried,. 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?

Rewards
You will receive: (at 80)

Progress
Did you meet up with the courier?

Completion
Why would Twilight's Hammer take an interest in these tablets? Brann himself wrote that he hardly knows their significance, although he did mention something about becoming one with the earth. I will need to confer with my fellow Explorers' League scholars to decipher these as soon as possible.

Thank you,. Without your aid, these tablets would've fallen into enemy hands.
