Khu'nok Will Know
Although you have acted valiantly in freeing the trapped calves, many of them will still die. You see, without a caretaker, these calves must fend for themselves in the wild.
But there is a way! Hope yet remains!
North of here in the mammoth fields, bordering the Scalding Pools, you will find Khu'nok the Behemoth: a mammoth as wise as he is ancient. Take this mammoth orphan and present it to Khu'nok. He will know what to do.
