Katan'asanka
The blade usually given to the third Sensei of the Eternal Dragon Temple, Katan'asanka is a powerful weapon. I came to acquire it in a trade with a thief, who I later killed, keeping both the sword and my collection of rubies. Since most Ninja blades lend special powers, Katan'asanka was made to tap into those powers. It can perform any of the abilities of the other blades, but there is a drawback. It has a limited supply of energy, and if it is used to access the powers of another blade, that energy is burned quickly. However, Katan'asanka has its own powers, namely, those of shadow. It can create a globe of shadow that hides anything and everything within until the blade's power runs out. It can send a wave of shadow at pursuers, blinding them for about five minutes and rendering their vocal chords inoperative. It can also cloak the wielder in real time and light, meaning that he can move anywhere and not be seen. Also, the cloak cannot be penetrated by magic, and the only creatures that have been known to sense it are those with high sensitivity to sound, or Oracles of intense power, who can feel the disturbance across the web of life. Katan'asanka is bound to me, and it cannot be touched by any other than who it is bound to.
