Prospector Whelgar wants you to scour the excavation site in search of the 4 missing tablet fragments: Ados, Modr, Golm and Neru.
Just before the invasion I uncovered a large tablet called the Goaz Stone. The translated text breaks off in 4 places. The text speaks of a "divine plan" and a "doomed prophecy."
I fear we are running out of time. I am too old to go down and brave those beasts. But you are strong.
Scour the excavation site and uncover the 4 missing tablet fragments: Ados, Modr, Golm and Neru. Search for them in ancient artifacts or where the soil is loose. Bring them to me so I can begin unlocking the mystery!
