The flight to Geonosis wasn't long. Hyperspace was a capability of Jedi fighters, after all. The high council selected two hundred and twelve Jedi Knights and Masters to form a strike force in order to spearhead the Geonisian campaign. 

Master Arven, a Mirilan Jedi Consular, was a part of the strike force. He very much liked flying, but there was no joy expressed on his face as he and two hundred and eleven others approached what may be their deaths. [i]Why would the Jedi council send two hundred Jedi to save three and investigate Geonosis?...[/i] "Hmm..." [i]They know that even two hundred of us cannot take a planet... perhaps there is a deeper plan that we haven't been informed of...[/i] 

The sound of blaster fire interrupted Arven's thoughts. He looked out of his cockpit and saw the vast space above Geonosis. He began whipping his head back and forth, he spotted them - perhaps forty droid tri-fighters, scattering. They had just shot down two of the thirty Jedi fighters escorting the two RTTs, or Republic Troop Transports which carried the rest of the Jedi. Arven maneuvered his fighter and fired his cannons, he'd hit a tri-fighter. It had continued for a time, fire grasping the fuel but sputtering out eventually because there was no more fuel to feed it. The tri-fighter stopped and it exploded after another Jedi fired at it. 

The battle lasted only a few minutes, but the Jedi had already lost four of their own. Luckily the droid's distress signal was jammed by one of the RTTs. When the Jedi finally landed, they were met with resistance from the droid army. Mace Windu immediately sprang from his RTT and targeted the droid communication arrays. 

Arven sat in a RTT with about one hundred other Jedi. They were instructed to not leave the transports, they didn't want anyone to know that Jedi were attacking, if Master Windu failed in destroying the communication arrays. Needless to say, Windu hadn't failed. He and Master Luminara Unduli piloted the two TX-130 saber-class tanks, which each RTT had carried in their respective cargo bay, they cleared a way for the Jedi to the Geonosian arena where they had tracked Skywalker and Senator Amidala. 

Master Arven stepped out of his transport. They were being dropped off near the arena, each Jedi wore their cloak and hood in order to conceal themselves. Arven Geonosis was not a pleasant place. It wasn't quite as much of a desert as Tatooine but more of a canyon wasteland, there was no moisture anywhere, Arven could feel that much, his throat was instantly dry and became scratchy. All the same, he made his way into the arena. After traversing hallways and dark tunnels he was blinded by the sunlight. The arena was huge, it could seat quite a few thousand, and it did. [i]Where are they...[/i] He spotted a balcony and could make out a few figures. One wore Mandalorian armor. [i]That must be Jango Fett, the bounty hunter Obi-Wan told the council about... That man next to him...[/i] He spotted a tall man wearing black and a scarlet cape. [i]It looks like Dooku... It must be him...[/i] Arven felt only pity for the former Jedi Master. 

Arven sat in the crowd, cloak still over himself, he did his best to not draw any attention to himself, but he kept an eye on the balcony. He knew that Obi-Wan, his padawan, and Senator Amidala were in the arena, about to meet their execution, but he waited. Master Windu said that there would be a clear signal to reveal themselves. After a while of waiting, Arven saw the Geonosians bring out their beasts. There were three of them, an acklay, a nexu and a reek. They attacked the trio, Skywalker mounted his beast, Amidala climbed to the top of her post and Kenobi did all he could to avoid the acklay. 

Arven saw Windu on the balcony, he drew his lightsaber, the purple blade distinguishable, even from this distance. Arven stood, threw off his cloak and drew his own green saber, the blade emitting a soft hum. He saw over two hundred other sabers of many colors ignite around the arena. Arven jumped into the air, high above the enemy and landed near Senator Amidala. There were already a multitude of droids pouring into the arena. The other Jedi did the same and within moments a full scale battle had erupted. Blaster fire came from every side, but Arven had mastered Soresu, he did his best to avoid blaster bolts and deflect them back to their shooter. He saw a Jedi jump to Dooku's balcony but was immediately shot. Arven made his way to the balcony and jumped to it. He was immediately met with blaster fire from Fett. Arven deflected it and used the force to snatch Jango's blaster from him, tossing it into the battle below. The bounty hunter dove after it.

"Ah, Master Arven..." Dooku's voice filled Arven's ears. The, now, Sith lord gave the Jedi his undivided attention. 

"Count Dooku. It would seem that we are on different sides of the same battle, my old friend." Arven's voice gave off a cheerful tone, but his expression gave no such tone. 

"I will offer you this once." He paused. "Join me, turn to the dark side of the force. Become my apprentice, together we can destroy the Sith Master." 

"You must know that I would never turn to the dark side Dooku, so why ask?" [i]So there is a new Sith Master... This is most troubling. If I make it back to Coruscant, I need to inform the Jedi council of this...[/i]

"Them you will die." Dooku's expression changed from neutral to anger. He stepped aside and super battle droids emerged from the hall behind him. 

Arven drew his saber and began deflecting the droid's baster fire. He jumped over Dooku and landed in the midst of the droids, they didn't have enough time to react. Arven systematically sliced through them, after just a few seconds all that remained was a pile of parts. 

Arven turned to Dooku, who was to be the only other on the balcony by this point, the separatist leadership must've fled. Arven decided to employ ataru for this battle, his second form. He skipped the opening stance and moved straight to the attack stance, saber held over his head, one leg outstretched toward his opponent, the other supporting his weight. 

"Ah, ataru. I see Master Yoda has had a hand in your training." Dooku had clearly recognized the stance.

"Yoda has no hand in my training. It is Jedi tradition that Mirilan padawans have Mirilan masters. I have been learning ataru for many years, recently I have mastered it." With that, Arven launched himself forward and began his assault with short, coordinated saber strikes. Dooku's makashi form easily redirected each of Arven's slashes. [i]Falling Leaf...[/i] Arven had learned the falling leaf technique recently. He outstretched his saber, brought in his other arm. [i]Left foot... jump... spin... land on the right... repeat.[/i] 

Arven and Dooku locked blades. "You have lost, my old friend - the Jedi are weak and losing numbers. Will you help them, and die? Or will you continue fighting me, and die?" Arven knew that the count was right on one account - he was no match for Dooku. Arven had made up his mind. But before he could flee, Dooku shot lighting at him. 

Arven brought up his saber to absorb the lightning. Dooku used the force to take the saber from Arven's grasp, he tossed it aside. Arven held out his hands [i]Yoda did teach me this... I lied to Dooku, but he was wrong... Yoda did not teach e my saber form... He has been teaching me tutaminis[/i] Energy absorption and deflection through the force. He shot his hand out and caught the lighting, he could feel it coursing through his whole body, but it didn't hurt. He was doing it right. Yoda had told him to think of it as though his hand was a rod, drawing in the lightning. He redirected the lighting and fled to the arena to aid the Jedi.
