"Xane Xane Xane Xane Xane," Rashir said shaking his head, "You don't listen do you? This world has the greatest source of light in the universe. It called me here to do something only one other keyblade master has done before. Besides, someone had to teach Shinji a lesson in betrayal" His keyblade appeared with a shimmer and he held it out in front of him, "You see my keyblade has been asleep and dormant this entire time. And now it has awakened its full power, the power of light!" He started spinning it with one hand out in front of him and it started to glow. "The last keyblade master that had awakened his keyblade let himself fall into darkness to seal the door, kinda like me but it was to save a friend. The darkness he had controlled was not as strong as mine so it was completely expunged, but mine has not." He put his arm above his head and spun it more and it started glowing brighter and brighter. It soon came to a blinding light and the figure of his keyblade was gone, it was now just and oval of light. He stopped spinning it and held the tip upwards. "Now it is time for you to face the light!" He flung his hand outwards and the light shattered off of the keyblade showing its true form.

The blade shined from hilt to tip as Rashir stood staring at Xane. He could feel King Mickey's presence flow through him and he could hear the king himself speak to him,
"My power is now yours young one. Use it to help your friends and save your mother." Rashir said quietly back, "I will." He took slow steps towards Xane while talking, "The spirit of King Mickey himself lies within me now." He disappeared and reappeared closer to Xane before the after image had gone away. He did it multiple times before he was out of sight. Where he had stopped only he knew.
((And just so we're clear L did give me permission to do this if you are a bit confused.))
