Asheron's Investigator
From Drunkapedia
Asheron's Investigator tells you, "My Master Asheron has been in discussions with your Queen about the Patriarch Raids. She sent Scouts out to collect the same stones the Patriarchs sent their minions to collect. Once we have enough of the stones to test we may be able to discern the Patriarch's reasons for collecting them."
Asheron's Investigator tells you, "Help the Royal Scouts collect the stones and then return to me."
