The year is 2029. The Huntley Scientific Research Institute has opened its doors to a select few—young individuals gifted with extraordinary mental powers and mysterious abilities.

But what begins as an exciting opportunity quickly spirals into something far more dangerous. As Ziek uncovers the secrets buried within the institute, he realizes his carefree life is over. A deeper conspiracy is at play, and he’s already entangled in its web.
