Riol once numbered amongst the famed Company of Heroes. His role was chiefly reconnaissance, and when the sellswords set out to defeat the primal Titan, it was he who discovered a hidden means into the kobolds' rocky stronghold. After the Calamity, Riol briefly worked as a freelancer, covertly imparting his knowledge to the Warrior of Light and his allies when Titan was again summoned unto the realm. He was among those who joined the Crystal Braves at Alphinaud’s behest.
