A group of Spec Ops operators are saved from the jaws of death by the intervention of the Supreme Law of Time. After waking from a coma, the team's leader finds himself bound to an alien symbiote. And thanks to the symbiote, the team is thrust into the hidden world of Will awakeners; individuals who use their Will to harness superhuman abilities. 
As if that wasn't bad enough, the team accidentally uncover a conspiracy by a powerful shadow organisation which then puts them in the central position in the fight against the organisation and their nefarious plans for the world.
Thus, begins the journey of the Soldiers chosen by Time!

Soldiers of Time.
