Man of Many Waters (The Saga of Fastillion Lemonde Book 2)

In a sword and sorcery world of giants and dragons (which don't appear until book IV) where history and mythology are equally real (the overall premise - the local legend and mythology of each location in the world is actually happening and coexisting with history), the world (whole world) trekking saga of Fastillion Lemonde begins on the Isle of Vinland during the Viking era of their colonization of the Americas (11th Century). When an ancient tribal enemy returns armed with the black magics of the (cannibalism fueled immortality) Windigo shamans, the viking Norsemen and their native Micmac allies must shake off generations of lazy peaceful living to once again take up their warrior ways. From the author of the nine (ten here soon) books of the Gravewalkers zombie survival horror series.

While undergoing his ceremony of manhood, Fastillion has spirit visions where he witnesses the fantastical events that bring about his own conception among the travails of an exotic fallen psionic empire in Mesoamerica, a people who are the last dwindling remnants of a superhuman Atlantian race.
