The year is 2012, Luis Oden is about to graduate as an Aerospace Engineer and he expects to be chosen to participate in the ambitious Project Hermes, to develop a new generation of space shuttles in the new European Aerospace Center of Seville, Spain. His life is seemingly perfect until he begins to suffer recurring nightmares where mighty beasts, that seem to come from the Norse mythology, assault and torture him urging him to wake up. But wake up to what?
Meanwhile, Jack Preston, a Lieutenant Colonel from the USAF and responsible for the tests of the X-56 Phoenix, a prototype of an orbital superiority combat jet fighter, is sent together with his crew to Seville to review the development of the Hermes program. There he will meet Luis when they are chosen to star the parachuting exhibition for the Columbus Day.
Both Luis and Preston ignore it, but a dark menace is coming and only their choices will be able to give a chance to humanity to survive.
Jack Preston and the survivors of the #DisasterSeville try to rebuild their lives and put the pieces of the enigma together. Why did they attack them? Who are these aliens and their saviors? Is the Earth still in danger? Who is behind the mysterious disappearances after the battle? Is everything connected? Meanwhile, Luis will wake up in the Valhalla ship confused and surrounded by strangers who treat him as if he were a reborn god. He will have to go a long way across the galaxy. An epic journey that will lead him to discover not only who the Order of the Valkyries, the Borean Federation and the terrible Hekkar are, but who he really is and what his role is to save humankind before the end of time, before Ragnarok.
After the tragedy of the Trial of the Valkyries Luis has been badly injured. He needs to recover and return with the Valhalla to Borealis to ward off the Hekkar threat. Will Luis be able, with the help of Freya and the Order of the Valkyries, to save the Borean Federation and, with it, all of humankind? It may already be too late and the darkness has spread to the very heart of the Borean Council.
Meanwhile, on Earth, Jack Preston and Kira Takeda will have to discover who is behind the attempted sabotage at the Earth Defense Center. Only one person can unravel the enigma, the cold and deadly ‘Katana’. Who will have to choose between loyalty to her clan of assassins or help Kira and Jack to ensure the future of humankind. No one of them knows, but time is running out. The battle of the end of time is closer and closer...
