It's been five years since the Legendary Hero of time was slain by the Dark Sorcerer Ganondorf, and the lands have fallen into despair. With the Gerudo at his disposal he attacked the rest of the lands, starting with the mighty Gorons. After months of fierce battles they fell, making Death Mountain in Ganondorf's rule. Next he turned his attention to Lake Hylia, moving his forces into Zora's Domain. The zora's fought bravely, but in the end, fell with the death of King Zora XVI. Any remaining Zora's and Gorons fled and found themselves inside a deep forest, where the Kokori children found them, wounded and near death, and brought them back to the village. To this day Ganondorf has not found, and has given up on finding, the Kokori Village. Plans to burn the entire forest down are underway. Once his forces start growing low, for example: after the battle with the Goron people, Ganondorf simply took townsfolk from any of the remaining towns and turned them into monsters under his will.
And yet, Hyrule wasn't the only land that was affected by the death of the Hero Of Time.....
Termina befell a horrible fate, Majora's moon fell upon the city of Clock Town and all off the area's inhabitants. Instead of killing them, they where turned to mindless Ghouls, slaves to Majora's will. Those unaffected by the magic are still missing. Not even the four guardians of the land could stop Majora, and where slain by his hand. The Zora and Goron banded together and attacked Majora's forces, but where quickly overrun and turned to Ghouls. The forest of Termina is no more, Majora burned it to the ground and took any survivors as slaves.
Three years ago Ganondorf sought to control Termina as well, and found the gateway to that world, then proposed a "friendship" of himself and Majora, letting them rule both lands. Majora declined his offer, saying that "any friendship we have would be as you as my second in command". Ganondorf, humiliated and full of rage began sending his forces to Termina, declaring war on Majora....
This war still rages, and thankfully Ganondorf has forgotten about us Kokori Children here in the forest.....for now..
