The danger that Sin had sensed was not the potential of the rangers. Or even the backing of the Free World Alliance, as the prim minister of the had just chimed in on the holonet. No, what he sensed was several guards. Two more pig men, and two droids. Moving up the stairs with reckless abandon. Killing Cardu was but the first victim.
"Company coming puppet." He spoke to in her mind.
Reaching out with the shadow of the force, Sin would lift the Gamorrean door guard. Tossing him like a bolder down the stairs to stop or at least hinder the advance of the others. Turning to where he noticed the crystal from before, he reached out once more. Pulling the un-bled crystal to his hand. Quickly then, with the aid of the force he held the hilt before him. Dismantled it, swapped the crystals, and reassembled the weapon.
Activating the weapon as the first guard came up the stairs. Sin would activated the green blade. Then force pushing the pea brained guard back down the stairs. Then looked around to see a mask. This was sloppy. He knew it. The ren demanded to be replenished. It hungered, and that hunger was feeding Sin's anger.
"Now!" He roared in Jez's brain.
He would not wait however. Instead charging forward. His anger seething from him. The shadow building within, bubbling like lava in the veins. Waiting to explode. And when he got to the stairs it did just that. The saber in his left hand, his right hand shot forward. His hand formed a claw like cone, the center of which would erupt a cone of fire that would fill the stair case. Enveloping the three living guards in fire, causing them to panic and tumble down the stairs. Falling on and almost melting to the two droids.
