Entry 001 - Creeper (furtim occidere)
The Creeper is considered by many the most terrifying mob in Minecraftia. This is because of its alarming stealth and the ominous hissing noise it makes as it primes itself for destruction. Being a very dangerous mob, it is often hunted and it is widely advised that new users avoid them. But this was not always the case.
At one point, the Creepers were allied with Minecraftians. In fact, they were around far before Minecraftians came to be. At first the Creepers were very helpful. They showed people how to make fire, how to use caves as shelter, and how to cook food. A few Minecraftians even took Creepers as their wives, seeing as how their biologies back then were similar enough to accomodate this interaction. They created hybrids, and today a small percentage of Minecraftians are direct descendants of this line of half-Minecraftian-half-Creeper offspring.
But soon relationships began to sour. It started with a man who called himself a prophet, a man Minecraftians called Dinnerbone. He preached that soon the Creepers would rise up and take control of the land, driving Minecraftians out of their homes and killing all who dared oppose them. Naturally, as with any slander, the Creepers protested. But the prophet Dinnerbone's words resonated within the hearts of many Minecraftians, and soon they took up arms against the green creatures. The Creepers tried to hold them off, but due to their lack of arms (an advantage in evolution at this point) they were quickly driven off.
Ingesting a mixture of sand and gunpowder, a few brave Creepers decided to fight back with a futile suicide mission. They raided the villages at night, and exploded when the number of casualties would be highest. Dinnerbone considered this a fulfilling of his prophecy, and the Minecraftians hailed him as their leader. With his help, the Creepers were driven back into the caves and the forests.
Today, due to their habitual diet of a mixture of sand and gunpowder, they have evolved so that their very blood is an explosive. They now no longer have any choice but to explode on meeting a Minecraftian; it is chiseled into their very heredity. That is why, when a hitherto smiling Creeper pup is told by its parents what its destiny will be, they develop a deep frown that within a week is permanently etched onto their faces.
So you see, it is not the Creepers who are at fault for our continued fear of the armless quadrupedal monsters. It is us.
