The young padawan couldn't find another exit. This was the end of the road. There was no Sith. There was no further path. They would have to return the way that they had come and face whatever dangers may be on the return trip. Isen looked over his shoulder and saw his teacher, Izel Thral prepared to put this former Jedi out of his misery. Isen knew now, with no other path, that he die was cast for him. He also figured that with Izel's deep connection to the Force, and was far more likely to feel this man's life force, killing him would be harder on her than it would be Isen.
Isen nodded to his Master before taking his own lightsaber and cutting the lifesaving cords that connected him to the machines. He would die soon, and there would be no question that Izel's action would be a mercy and a service to this person. With a mixture of emotions about what he felt compelled to do, he disabled his lightsaber and made his way back through the hole through the door that he had created. He stared at the carnage of this room. The exploded, gooey, acidic remains of the Terentatek were splattered all over the room. Isen ran a thumb over the obsidian stone that the beast had left behind, unsure of what it was or if it would ever be needed. He did not forsee these types of decisions needing to be made when he started his Jedi journey. Here he would wait on Izel Thral, the deed would be done. And hopefully, they would meet up safely with their allies that they started this mission with them.
Nar ShaddaaIzel nodded to Isen as he cut the cords. Well that was that, he was a dead man now. All that was left to do was finish him mercifully. As her Padawan exited the room she turned her attention back to the Jedi on the table, taking one of his hands in hers. As much as time was of the essence, some respect was still due to a fallen comrade. "I'm sorry." She told him softly. "We will put an end to this I swear it. No one else will suffer what you have endured. May you be one with the Force." She pressed her pike to the underside of his chin and ignited the blade, hopefully killing him instantly and painlessly. After extinguishing her lightsaber once more Izel took a moment to check the Jedi's pulse, to ensure he was no more. Once satisfied she turned and left the chamber herself.
Outside she found her apprentice waiting for her, and was gripped by a sudden pulse of disbelief. "Why are you still here?" She cried, although her tone indicated more desperation then outright anger at her Padawan. "I told you to go on ahead of me to regroup with the others! Did you not hear?" With an exasperated huff she summoned the Force again, though her energy reserves were running dry, and augmented her limbs so she could move more quickly. "Come on! I can already feel the Sith presence we have to get back to Nara!"
With that she broke into the fastest sprint she could manage in her current state. She didn't know how useful she'd be in a fight as she was, but she'd throw everything she had left at the enemy, if she only got the chance. Isen she knew would be able to put up a much better fight. He was less injured and skilled with the lightsaber, but his hesitation had cost him valuable time. Hopefully now he would be willing to rush ahead of her and engage the Sith, though she had no idea what lied ahead. It could already be too late.
