Tenchi was four years old when they came for him. Despite the best efforts by his mother to keep him hidden and safe, he was taken by force to Juneau Gardens, which is the home of the Homospiritus and the new governing order of the former United States of America, now named Juneau. It is a Gardens itself, one of a series of peaceful and beautiful utopian societies made up of the now free Homospiritus who, under the terms of the Accords, were allowed their independence and sovereignty. Gardens are realms, which demonstrate the height of Meteora manipulation and the coming together of humans with Meteora to create a utopian, Shangri-La-like paradise on a level with the Garden of Eden. Now inside of Gardens, Tenchi is swept up in a world of Meteora, fighting, and war, to protect a world he does not really feel a part of. He is taken from his home, his mother, and the only family he has ever known and commissioned to fight in a war for the peace and safety of the planet. He is forced to go through rigorous training and trials, as well as torment from other Homospiritus, when the only thing he truly cares about is getting home to his mother. And, after six years in the Gardens' Academy comes to an end, he seems to get his chance when, at the age of ten, Tenchi graduates. Now he is an apprentice, under the command of a Master Agent who guards, trains, and protects him and his two other apprentices, Ko and Suki. In the field as a second level of training, Tenchi has a greater degree of freedom, though under the careful guidance and tutelage of Master Agent Shaun. The team members begin their journey all over the world carrying out peace missions while simultaneously improving and learning how to better use Meteora in real-life battle situations, all to prepare the young Agents to eventually go out on their own. This is vital, as it is public knowledge that the life of an apprentice is a very short one. Tenchi is then swept up in a series of missions, both dangerous and important to the fate and the safety of the whole world. Eventually, he is sent on a mission where he encounters terrorists with nuclear arms who have also taken their own dark dive into the use of Meteora, only to corrupt it. Tenchi is given the chance to abandon his mission and continue his own, which has always been to return to his mother. But now he is faced with a choice, to return home or to fight to secure and prevent the misuse of The Sword of Heaven, an ancient weapon of unparalleled power forged of Meteora itself. If not kept in check, The Sword will throw the world into an apocalyptic age from which we may never recover, a fate that will visit both Homospiritus and humankind alike.
