An unofficial minecrafter's adventure With his sister stuck in Minecraft, Gameknight999 will have to face a new enemy to save her! Gameknight999 was sucked into the world of Minecraft when one of his father’s inventions went haywire. Trapped inside the game, the former griefer learned the error of his ways. He transformed into a heroic warrior and defeated powerful endermen, ghasts, and dragons to save the world of Minecraft and his NPC friends that live in it. Gameknight swore that he’d never go inside Minecraft again. But when his little sister, Monet113, accidentally enters the game herself, the User-that-is-not-a-user has no choice but to return to a digital world where very real danger lies around every corner. With the help of some old friends such as Crafter, Hunter, and Stitcher, as well as a few unexpected new ones, Gameknight will journey deep into a zombie village and face Xa-Tul, the powerful zombie king crafted by a shadowy figure with bright glowing eyes and a hatred for Gameknight999. To save his sister, Gameknight will have to learn a few new tricks if he has any chance of defeating this monstrous creature.

An ancient jungle temple holds the secrets to stopping the evil Herobrine! Gameknight999’s true enemy has finally surfaced: Herobrine, an artificially intelligent virus that wants to escape Minecraft and destroy mankind with their own creation—the Internet. If he is able to escape the game and get online, Herobrine will infect millions of computer systems and turn machines and weapons on their masters, threatening all of humanity. After facing Herobrine in battle and nearly dying, Gameknight realizes he’s going to need much more help to defeat this seemingly invincible enemy. His NPC friends tell him of the ancient Oracle residing in the oldest jungle temple in Minecraft who knows the secret to defeating this terrible threat. The path to the temple is fraught with danger, with zombies, spiders, and creepers lying in wait behind every tree and bush. Gameknight will enlist the help of his friends on his quest, but will they reach the Oracle in time to stop Herobrine? Gameknight999 will be tested to his limits, and perhaps beyond, in this spine-tingling new adventure.

The final battle to defeat Herobrine will take Gameknight999 over land and under water! Herobrine is rallying all the monsters of Minecraft to one server in hopes of eliminating Gameknight999 and his friends once and for all. They destroy every village they find, threatening to continue until the User-that-is-not-a-user surrenders. Gameknight has just two things: the Oracle’s command to seek out the lost ocean monument and an impenetrable riddle: “Look to the lowliest and most insignificant of creatures, for that is where your salvation will lie.” Haunted by this seemingly useless clue, Gameknight searches for the mysterious underwater lair where the Book of Wisdom is hidden, which he is told holds the secret to the riddle and the key to defeating Herobrine. But at every turn lies a massive army of monsters. With no map to guide them, Gameknight and his friends will fight for their lives to reach the deep ocean destination, and a terrifying creature awaits them there. The Mystery of Herobrine series comes to an explosive conclusion on the shores of Minecraft, where one false move could spell the end for Gameknight999 and company!
