'Kori looked around, trying to find the source of the rustling before it stopped. That's when she spotted the yellow cat-like eyes. She stared at them, moving back. The creature made a low, rustling growl, inching forward slowly. When it spoke, it was sickly sweet, like a purr from an angry cat. "Daughter of Hades," Kori suddenly realized she knew that soothing voice and aimed her arrow at the eyes. The creature chuckled. "No, sweet child. It will take more that a pesky arrow to defeat me. Besides," the creature emerged, a thick void of black shaped into a large cat. "I know where Ember is."'
Hades and Hekate created a powerful stone to hold a rare species of flames called Ember. Once created, Hades entrusted the stone with a human he fell in love with. 18 years after the creation of the stone, Hekate is missing, the Protector is dead and the stone disappears. Hades recruits 10 heros to find it before it lands in the wrong hands. Little do the heros know, Ember is a lot closer to them than they were led to believe.
