Sunspire Mountains where to find the missing piece of the puzzle

Once upon a time, a fearsome beast seized a shadowy child and slammed him into the ground with enough force to kill a more fragile creature, laying him low for weeks and revealing her own unhinged savagery.

Nyra was no longer a snowy beast, but a hulking coward. And Aventus was no longer a shadowy boy, but a sinewy reaper. He lacked the innate violence of his family but that did not make him weak or hesitant when his sights were set upon an enemy. There was no greater enemy than Nyra, and so the second wolf with her went utterly ignored. If he had time to think, he would wonder why this wolf continued to side with his cowardly companion. Surely he had seen how she fled and left him behind.

Aventus had no time to think. He only had time to swing around the woman, leaving Merrick to her face. His father was a berserker in battle, and Avicus surely close at hand, as well. He joined his family in splitting her attention three ways, did what wolves did best and lunged for her hindquarters, intent on sinking his teeth in as deep as they would go to make her bleed

And bleed

And bleed until her body was an empty husk.
