Only Snow Remains

Eliminate the Urun and the Rebel Werebears, and defeat Beorn.

Beorn… His fur has long since become white - not from birth, but from gray hair. The old leader lived three lives of a bear.
He won't talk to you unless you show him your strength. Go and finish what Yor started.
Those indoctrinated by Beorn will stand in your way. White cats are among them. They will come to your land. Very soon.
Don't let your hand falter, outlander.
Even if only snow remains on the cliff after you.

Kharyskhan did not lie when he promised Beorn immortality... Now I see!
