Canyonlands Divided

From the introduction:

The adventure is set in the Canyonlands of Xāllital, named Corvidae Canyon by the locals, where the party will meet four tribes that have been displaced by the Rupture. In the one shot, Crisis with the Condylura, the party helps one tribe, the Vernali, with a monster problem. As they investigate, they learn of a much deeper, darker secret preying on Corvidae Canyon. The rest of Canyonlands Divided explores Corvidae Canyon in more depth as the party meets the other three tribes and finds themselves in the middle of an impending war.

Is conflict inevitable, or is someone, or some thing, pulling the strings?
