Sylvanus: Rise Of The Demon

On the breathtaking island of Ortet, where the winged Skybourne and the grounded Groundstay live centuries-long lives, ancient peace is shattered by the return of a terrifying monach: Sceagga. Corrupted by the forbidden dark energy known as gray pacú, he was defeated six centuries ago, only to reemerge and force his dark essence upon the Haloguardein Yelu. She survives the assault to give birth to twins, Michael and Lucero, one of whom is believed to be the promised savior. But Sceagga is patient, and the path of prophecy leads the siblings through a dimensional portal to Earth's ancient past. There, unchecked power warps one of Yelu's sons into a demon, forcing the other to follow across worlds for a desperate confrontation. When the ultimate betrayal is committed, it is Dancing Elk, a young warrior from an ancient tribe, who is revealed as the true Promised One. Armed with only the magical staff Nenemehkia, he must chase the corrupted twin to the ends of reality and contain the growing darkness before all worlds fall.
