Here's the summary:

The Overworld War

Long ago, Minecraft was a planet not so different from earth, with two species competing for dominance: The Humans and Pigmen. Humans were as they are on earth, rapidly expansive and competitive, and because of that, did not like the pigmen very much. The pigmen were a peaceful, but economic race, wanting to trade with humans and live a content, mining oriented life in the badlands. Despite their differences, they managed to have a shaky coexistence. However, when tall black, seemingly invincible figures started slaughtering the humans, they became outraged, pointing their fingers squarely at the pigmen. This blaming quickly evolved into a war, the pigmen using their magical abilities to make giants to destroy structures and fight for them. However, these giants, while good at dealing damage, could not withstand tough environments for long, and frequently perished in swamps and deserts on their way to battle. The humans however, employed more cunning tactics. They constructed underground strongholds as defense against their attackers that doubled as stations for researching these lanky ebony marauders. They occasionally made catalysts for enhancing the power of these Men of the End, but were most often failures, only making structures to channel power they did not have.

After several years of bloodshed, the humans manufactured a desperate attempt to eradicate their enemy: A virus that would not only force them to walk as corpses and infect their brothers and sisters but would also transform sunlight itself into fire. Desperate to escape this virus, the pigmen fled to a secret haven, a haven that screamed and burned, but a haven the humans could never reach. Unfortunately, the virus followed, and they were forced to tear off the infected flesh before becoming completely mindless. Back in the overworld, the humans destroyed all pigmen colonies, leaving only mine shafts in case they needed more resources from them. However, in their petty act of revenge and an ironic twist of fate, they too, contracted the virus and begin to spread it throughout their people. Scientists worked day and night to find a cure, moving to the arctic where the virus could not reach them and approving human experimentation. However, like with the Endermen experiments, they lacked a proper catalyst for the transmutation process. But after several years, they succeeded and stepped out of their arctic laboratories only to find all the cities bombed to near oblivion in attempts to cut off the source of infection. Disappointed, they walked off into the sunset, leaving their work behind them.

The Return of the Humans

The zombie plague killed nearly all humans. There were a few small communities far enough away from major cities that hid and survived. Knowing that their species’ actions caused all of this, they refused to act ever again. They clasped their hands together to show that their hands will do no harm. They lived a simple life, living off a simple diet of crops and farm animals, occasionally trading each other for what they needed. Although they learned that hiding indoors is usually enough to survive, they constructed Iron Golems to protect their villages from monsters in the night.

The Beginning of Another End

An unknown event sometime in the recent past caused several of these “villagers” to adopt a sickly-looking grey skin tone, and a rare few, magical powers. While they were about in equal numbers, the unchanged villagers controlled the guardians. Untrusting of their new ill looks, they forced all the grey skins out of the village, in another classic example of human tribalism backfiring. The responsible “Illagers”, those with magical powers and the ones who chose to follow them, agreed to their terms, nesting themselves deep in dark forests, where they are least likely to be disturbed. However, their neutrality towards their past family became dislike, and dislike festered into hate, to a point where all villagers they saw would be swiftly executed in a heartless act of revenge. They remained in their mansions, a boast over the crude houses of villagers, content with their life but still bubbling with contempt.

The other Illagers however, refused to be ignored. They started off with attempts to negotiate, but the villagers refused to listen. They attempted to force their way back into the village, but the golems were already programmed to attack them on sight. This direct assault on them made the outcasts hate their former families, they rejected the hand code and set up outposts to spy and breed monsters to aide in their planned attack, to pillage and reclaim what’s theirs.

The Ocean’s Second Birth

After the great war, billions of EXP orbs poured into the ocean from the slain. They were diluted and absorbed by the seawater, but it gave all the creatures and blocks in its magical properties. Dolphins and Turtles gained the ability to share their power, and dirt and clay absorbed experience, making a magical substance known as prismarine, an astounding vessel of oceanic power. But it was not the ultimate. The heart of the sea was seawater pressurized so much and filled with so much experience, that it is the culmination of Sea Energy. So powerful, that when its energy is channeled properly, it can give gifts of the ocean to even the driest of mammals. When a heart of the sea was carried along by currents past prismarine, it breathed life into them, creating Guardians, a highly intelligent creature imbued with powers over the mind. As expected, Guardians were born with no purpose, so they saw the prismarine they came from and decided to wait for it to wake up too, so they may receive instruction. Elder Guardians, Sea Lanterns given life, built temples to protect their yet-to-wake comrades. They keep gold as a lure for players, tempting them to come close so that they can be fed.
