Atlantis Bermuda Triangle

What if the force that destroyed Atlantis so utterly it became just a myth, is real and its back to threaten our present world?
Former Green Beret Eric Dane teams up with the mysterious Sin Fen, a woman with powers he can't quite understand, to fight the dark Shadow that is poised to destroy our world across timelines.
All around the planet, at the junction of ley lines and where tectonic plates join, interdimensional gates are opening, letting the dark Shadow into our world, threatening the very planet itself. This war is taking place between worlds and across time.
In the year 1,000 AD, a fearsome Viking warrior, Ragnarok, must protect a Seer from Valkyries, Kraken and other forces of legend and help her on a quest that connects through those gates to Dane's battle in the present.
Can Dane, Sin Fen, the Viking and the Seer, combine forces across a millennium to save the planet?
