Covering the space between them in the blink of an eye Quo feinted with his sabre towards Tasha'Vel's lekku. Her sabre flashing upwards to intercept his blade, she angled her head away, turning away and rolling to avoid the strike, regaining her feet, ready to accept his next attack. Looking round to acquire the Zabrak... where was he? He had suddenly slowed as he feinted, shut down his lightsabre, and disappeared.
Quo knew that this deception would not last long, the soft padding gave away his feet position, and when he reignited his blade, or made a sudden movement he would be visible again. Tasha'Vel would soon realise what he had done, and sense where he was through the Force. The vibroblade at her belt leapt free, and spun across the room, instinctively her eyes followed it as it arched away from her. Quo’s blade re-ignited as two throwing knives flew towards Tasha’Vel’s position. Her senses alerted, she leapt in a low trajectory, spinning as she flew, arms tucked into her body, hitting the wall, feet first, and rebounding. Force lightning flared from Quo’s fingers again, but too late, Tasha’Vel had already bounced from the wall, and was heading back across the room. He realised he was now visible, and moved to his left, as Tasha’Vel found her footing again.
Gesturing with her left hand towards the fallen vibroblade, her arm arched towards Quo. The blade, seemingly of it’s own accord, flew across the room towards, just as he gained a secure footing.
Tasha’Vel’s adrenaline was pounding around her body, her emerald eyes glinting, almost a fury within them. The blade she had sent towards Quo had almost found it’s mark, striking him in his prosthetic arm, the clang of the metal matrix being hit echoing across the hall. It did, for a split second, make her apprentice glance to check for damage, just the distraction she had been waiting for.
She sprang, fuelled by the excess adrenaline, and with a refined focus. Her lekku dancing like enraged vipers, her lips pulled back into a sinister smile, she closed the gap with terrifying speed. Her sabre lunge towards Quo’s shoulder was blocked by his own blade. With such speed and precision Tasha’Vel’s blade was a fury of colour, as she struck again and again. Quo was beaten backwards across the room, his whole attention on defending against his Master, her frenzy seemingly endless. Quo was losing, and losing badly. Without a rhythm to the strikes, Quo waited for a pause, however fleeting.
Tasha’Vel reached out for her vibroblade again, gesturing with her left hand, as her right carried out it’s lightning tattoo against Quo’s defence. A subtle gesture brought the blade, point first, towards her,... towards Quo’s back. It flew like an arrow, sinking into the back of his tunic.
A sudden image flashed across her mind, unspeakable fright for a split second. Fear, pain, terror, they all struck her as one, with a vision so dark it made her step back. Quo struck back, knowing that this could be his only chance. His sabre danced in short, staccato bursts. Tasha’Vel’s adrenaline rose again, with her sheer fear, and her already infused system, she struck back with vigour. Her attack was too strong for Quo to realistically defend indefinitely, but he put up a valiant effort, fighting harder than he had ever done before. Tasha’Vel gestured, blue static electricity vaulting from her fingers, striking Quo in the chest, making his body spasm, his sabre flying away from him across the matting floor. Tasha’Vel stepped towards him, a rictus of anger on her face, the lightning intensifying, her sabre completing one last strike, through the right side of Quo’s chest, appearing again out of his back.
Standing above the fallen Zabrak she gazed down at him, broken and gasping. The echoes of the battle dying in the hall. Her anger and her fear were subsiding. What had she done?
"His fist whipping out from his own centreline, the punch more from the elbow than from the shoulder."
"...dancing lightly across her sapphire skin."
