Vaapad is a channel for darkness, and that darkness flowed both ways. He accepted the furious speed of the Sith Lord, drew the shadow's rage and power into his inmost center -- and let it fountain out again. He reflected the fury upon its source as a lightsaber redirects a blaster bolt. There was a time when Mace Windu had feared the power of the dark; there was a time when he had feared the darkness in himself. But the Clone Wars had given him a gift of understanding: on a world called Haruun Kal, he had faced his darkness and had learned that the power of darkness is not to be feared. He had learned that it is fear that gives the darkness power. He was not afraid. The darkness had no power over him. But -- neither did he have power over it. Vaapad made him an open channel, half of a superconducting loop completed by the shadow; they became a standing wave of battle that expanded into every cubic centimeter of the Chancellor's office. There was no scrap of carpet nor shred of chair that might not at any second disintegrate in flares of red or purple; lampstands became brief shields, sliced into segments that whirled through the air; couches became terrain to be climbed for advantage or overleapt in retreat. But there was still only the cycle of power, the endless loop, no wound taken on either side, not even the possibility of fatigue."
