Stone-trolls have come down out of the Ettenmoors to settle in the North Trollshaws.
'There are more threats in the North Trollshaws than just spiders, ${PLAYER}. Stone-trolls have come down out of the Ettenmoors to settle here in the North Trollshaws. I have seen them encamped in large number at the ruins of Ost Belegram to the south-west of here.
'If you and your companions could deal with them ere they become a threat to the rest of the Trollshaws, I would be grateful.'
Stone-trolls can be found at the ruins of Ost Belegram, south-west of Thoroniel's encampment.
Thoroniel has asked you and your companions to deal with the Stone-trolls of the North Trollshaws.
Thoroniel is posted north-east of Ost Belegram, in the North Trollshaws.
You should return to Thoroniel and let her know that you have done as she has asked.
