Sigrík has let you borrow the tusk you found for him, with the mysterious markings on it. He suggested that a Lossoth näkijä's apprentice by the name of Mika, who lives in Norsu-hauta, might know what to make of them.
'I must admit, I've no idea what these odd markings mean. But there is a young Lossoth, an apprentice seer of some sort, apparently -- näkijä is what they call them -- who might know something.
'Mika has been on some sort of quest down in that mammoth graveyard, Norsu-hauta, just south of here.
'Would you go there and ask him about the markings.'
Mika is at Norsu-hauta, south of Zigilgund.
Sigrík has asked you to speak with the young näkijä Mika about the markings on the mammoth tusk you collected for him.
