Thunder Dome watching as you waste through the ground

The mountain shuddered beneath her feet, sending loose rocks scuttling down its steep face. Lightsun stood still with panic, legs stiffened and outstretched as an unsteady base for frozen body. Since arriving in these lands, they had become more and more alive, the shaking and quivering of the earth itself becoming stronger and stronger. Her gaze turned upwards, towards to the tip of the dome, and waited, worried, for it all to come crumbling down - but thankfully, amazingly, it stayed where it was.
    After she had left her old home, she had joyed at the wide spaces, freedom, and independece, things she could not have as part of her old life. It was not all perfect, obviously; meals were harder to come by and the nights were colder and lonelier without a kennel and companions; but she could not stand to return to her stifling home and that rope around her neck. However, standing there amidst this ever-present danger made her question why she fled the safety of that backyard in that quiet town. She wondered if it was shaking there too.
    When the mountain had calmed, she tentatively took a step forward, almost expecting her footfalls to reignite the summit's fury. The world stayed still and she grew more confident in her movements, and continued to skirt the side of the peak. Her aim was not to climb, but to get across the mountain and reach somewhere more hospitable. She had been moving almost constantly for weeks on end, and needed a break. Below her she could see a long, green expanse, and wanted to get there, but was not sure how.
    Lightsun paused to think of how best to tackle her predicament, when she heard a clattering of stones that set her heart racing. Again?! So soon? she wondered frantically, her eyes instinctively turning upwards; but rather than rocks falling, she was greeted by the form of a white wolf. She instantly perked up, excited to finally see another canine after all this time. She watched as he deftly descended the slope, and when he was close enough to hear she barked out, "Hey! Over here!"
