Billy is not a very obedient cat. His mother warned him not to play in the woods, but he didn't listen. One day, Billy finds himself in the Nether, a bizarre world inhabited by eerie creatures. Accompanied by a nearly cheerful spirit and a not-so-evil witch, he develops incredibly unnatural powers. But will these be enough to stand against Endernova's army? To save his friends, the little cat must rise as the champion of the Nether, just as the prophecy demands of the chosen one.
