Mason:
I am now too old and weak too even lift a spear. But my hatred towards those who killed my family still boils up like lava. I beg you, please obtain vengeance on my behalf. I will be able to die without regret if you bring me 100 Bloody Axe Heads from the Bloody Axe Elite soldiers.
You will find the Ol Mahums in the Plains of the Lizardmen, in the southern region of Oren. Head north through Death Pass into Giran and you will find their barracks.
