-Its resilience, stubbornness and spirit unbroken, and searching for long hours to find those willing to <em>join</em> its cause.<br/>
-The old nest abandoned, the death throes of the Beast ignored, and more determined than ever to find glory in the future.'>

+In the trees, roots, animals, and even the <em>mountainous valleys</em> that had always been an <em>oasis of difference</em>.<br/>
+Still, our dragon continued, untainted and resolute, soaring above.<br/>
