Yokut was a Human hunter whose hunting party was ambushed and slain by the twisted magical beast known as Madcoil.
As with the other members of his party, he was dealt fatal wounds by the creature but survived long enough to describe the creature to a rescue party. The tribe's Shaman used this as further evidence that Elves were "demons" whose magic corrupted the creatures of the forest that the human tribe had taken as their sacred land.
Unknown to the Shaman, he was only partly correct and he himself had played an unwitting part in Madcoil's creation. The hatred between himself and the Elves' chief Bearclaw had stimulated the pool of corrupted Elven magic that had created Madcoil; indirectly making them both partly responsible for the death of Yokut and its other victims.
