Herobrine

Deep within a prison built of stone blocks, the silence was broken only by the distant sound of chains and the rhythmic footsteps of the Marauders. At the heart of that abyss, chained by thick, gleaming links, lay Herobrine, the legendary being with incandescent white eyes. He remained motionless, like a sleeping shadow, a pumpkin mask on his head (this pumpkin mask has a kind of unknown enchantment that keeps Herobrine weakened and powerless to flee), his two hands chained with two pieces of Bedrock (the unbreakable and heavy block of Minecraft) that kept his arms outstretched to the sides. With a simple movement, Herobrine crafted a whetstone (an item that removes enchantments from items). With the whetstone, Herobrine managed to remove the enchantment from the pumpkin mask, and with the only thing that kept him bound now ineffective, the pumpkin mask broke, and Herobrine began to rise. The Pillager guards reacted, throwing large Tridents, but Herobrine easily dodged them even while chained. At one point, one of the Tridents struck the chain, freeing one of Herobrine's hands, which then freed the other. He threw the Tridents at the walls, using them as platforms to jump on. Arrows were launched, but Herobrine advanced, managing to hide under a wooden elevator. However, they cut the elevator chain, thinking they could stop him, but Herobrine appeared and knocked down the Pillagers as if they were mere straw dummies. Blowing up the bridge almost worked, but Herobrine climbed a stalactite with supernatural agility, grabbed some TNT, and threw it towards the Marauders, blowing everything up. Outside, Herobrine stood triumphant. His white eyes burned like eternal fire. The prison, now in ruins, would be left behind before Herobrine's freedom.

Idea from a video I randomly found on YouTube. Explanation: Now Herobrine has been freed. We're all screwed.
