Power of Two Jewels

Many millennia ago, when the world was first called into creation, and the first evil crawled from the depths of hell. The Gods and Goddesses of the ancient world devised a weapon of such purity that even the Shikon no Tama could be rivaled.
The Gods placed this great power within a small jewel. It’s power causing the jewel to glow blue. However, by placing such power within such a small capsule caused the piece to break and the power to escape. In their frustration, the gods planed forth and created another jewel, perhaps thinking that it was the tiny piece which had been at fault. However upon the creation of the second and it’s destruction.
Instead they tried once more. They placed the forth element inside of the jewel and still it remained strong. They decided that five had been to much for one small thing to carry and so, since you really cannot touch the fifth, they placed it within a great warrior.
They gifted this warrior with the jewel and off to battle he went. It has been passed on from generation to generation, through out the many long years. Until the death of the family who had been entrusted with it’s care. Those that had sought to steal away the powers had not taken into account that by killing the fifth element, so dies and disappears the jewel of elements.
