His egg hatches into a Red Lizard—cute but powerless and only used for pest control. Just as Jethro resigns himself to a boring life, a wrong turn during a Rift Training expedition lands him in a forbidden Rift zone.He barely escapes alive… only to wake up with a supercharged power: he can see the magic and mechanics of every mechbeast, right down to their origins!Here’s the catch: the ancient conqueror who once had this power wants it back, and he’s bringing an army of terrifying mechbeasts to take it.To survive, Jethro must build an army of his own, starting from his powerless frail lizard. But can a pest-control pet (and its rookie human) save the world?Let’s hope so, because our dear world of Nebulon desperately needs saving!

I’m still struggling to control the urge to crush the little creature that took you away from me.”
