Since the Great Battle there has been peace between the shape-shifting black leopards known as the Caanlin. In Gylman Ruse, where the last great chief died and gave birth to this lasting peace, a monster has risen that drains life from its victims. The Night Trials have existed as way to give the young power, and so three young Caanlin face the trials to become adults and face the threat. Join the Caanlin as they journey to protect their people from mythical creatures, civil war, insurrection, and sickness in Caanlin Running.
