Ouroboros Spine Looms but the Horror of the shade,

Tonravik lurched forward to tag him. The movement was quick, fast; and then, she was off, away from the pond they'd discovered. A test of endurance. Something drove her to this, but what it was could not be picked at at the moment. She slid downward upon the slick decline they'd recently climbed down, and only when she found stable earth did she begin to use her legs to bring herself into a run. 

The leader would not allow herself to be tagged so easily; she ran full-speed ahead, dirt flinging as her feet gathered good purchase where they could and destroyed it some thereafter. Nature would heal itself from her heavy-weight sprint; she moved onward, and forward, the clouds above keeping her cool.
