Eirikk

A human poacher who acquired large beasts for combat training. He was ultimately killed by his final acquisition, an enormous Owlbear nicknamed The Beast. His past affiliations are unknown, and though he spent some time at the Stag Lord's Fort, he was not one of his underlings.
Eirikk was always interested in bigger, stronger creatures and paid Kundal for the capture of a number of beasts including a brush thylacine, a boar and a tiger.
Although armed with a Ring of Bestial Friendship, Eirikk ultimately failed to tame The Beast. It's possible he was able to cause it to attack Ornisk for reasons unknown, but ultimately it killed Eirikk in its cave after its mate was killed. It's thought that the ring was cursed.
Eirikk seems to have worked with a number of other poachers who also died in the Owlbear cave.
