Bijuu and the Legend of the Tailed Beasts
Since the very first dawn of the this world there have been creatures roaming the lands with unspeakable horrid power to the extent that early man dared call these creatures gods. In total there were nine of these false gods with each of these having a certain number of tails seemingly representing their rank among themselves or their status of power. The fewer the tails then the weaker the beastie was then the rest of its kind, this would be the main trait that gave these gods there name; Bijuu or The Tailed Beasts. Both the lands and these people were mere toys to be broken and manipulated with by these Bijuu; those capible of speech demanding shrines or offerings to please them.
Like sand through an hour-glass time slowly slipped by as encounters with these creatures grew rare though the false goods did make themselves known whenever they choose to do so. What had been called gods at one point were now considered devils whom strived in their own personal desires be it the power they had on man or the sacrifices of fear and carnage they were offered. Soon enough these beasts began fighting amongst eachother believing that only one among them should rule over these creatures called humans. These battles lasted months, sometimes even years, destorying everything in their path be it innocent souls or the earth itself as death and disease spread like a plague through their brawls. And then he came.... the man had no true name nor a home merely being a wandering soul doing whatever he could whenever he could.
This man marked with stark gray eyes with concentric ripple-like circles around the pupils weilded powers not unlike the Bijuu themselves. It'd be this unknown stranger who would bring light to a darkened world possessing a solution to these Bijuu yet like the monsters themselves this solution called for sacrifices. The idea was that they would bound these creatures within mortal flesh though this called for a person to sacrifice themselve to be the container of these false gods. Jinchuuriki or "power of human sacrifice" were the names given to those poor souls whom would offer themselves to save their people from the Bijuu. Some of these creatures proved to be too powerful to be sealed into a human so instead their bodies were sealed to various shrines spread across the lands. An interesting side-effect to becoming a jinchuuriki was that the huamn would gain features and faint abilities akin to those of the bijuu inside their bodies. In case these jinchuuriki grew out of control or the Bijuu somehow freedom themselves from their seals the wanderer taught the people his own abilities. This was the birth of ninjutsu, with this lone wanderer being named the Rokudou Sennin or Six Realms Sage due to his six different types of abilities.
THE RESERVES
This is a list of all the Bijuu, a small piece of information on their appearance and powers, and their starting Bijuu Control level for Jinchuuriki's. This list also details how many transformations a Bijuu has, in order to keep Bijuu with tail counts under four on a similar number of transformations as other Jinchuuriki with similar control type.
