Lets take a look
Before 1:20 it sounded as if a wolf is crying out desperately for
(What I mainly think) a pack live beside.
And at 1:20 he may have found one and and the pack is for a large battle. At 1:52 they spot the enemies and charge at each other, the dramatic battle endures, then at 1:13 the wolf receives a fatal blow, cries in pain or for help then dies.
Great song tells a story in a way.
