Sylvanus: Book of Alce by R. P. O'Ryan
An ancient prophecy tells of the coming of the Promised One, who would restore peace and harmony to the land. When the twins, Michael and Lucero, are born, they believe one will be the Promised One.
The two are mandated to travel and spread the word of God, Eyu. Lucero travels to the outerworld, where he befriends Dancing Elk, a young Taloosh native, the next tribal shaman. Meanwhile, Michael remains behind to spread the word in his world.
Corrupted by greed, Sceagga, a powerful monk, follows Lucero. He tricks him into imbibing the dark life force, the grey pacú, corrupting his mind and turning him into a mighty demon, Sceagga’s tool for conquering the land. However, Lucero’s ambitions are bigger. Intent to conquer both worlds, he turns on Sceagga, who escapes the demon and returns to his homeworld. Now Lucero seeks the next powerful source of pacú, Dancing Elk.
Two years have passed, and no word from Lucero. Concerned for his brother, Michael travels to the outerworld seeking Lucero, and now Michael is missing.
As the demon’s rampage continues, the only one who can stop him rests on the shoulders of the young shaman-to-be, Dancing Elk.
So who did they say was the Promised One?
