The crash and boom of thunder announced the arrival of the Goddess of Thunder to the mortal who had summoned her. He was gravely injured: a large scorch mark on the left side of his face had ruined one of his eyes, and a hole had been burned through the right side of his chest, a fatal injury. The scent of burnt cloth and cooked meat hung heavy in the room - three others had also been cut down by a lightsaber. No, wait, the Nautolan mortal was only unconscious, not dead like almost all of the rest of her favored mortal's companions.
The last of them was engaged in combat with the mortal whose evil was rotting himself from the inside out, the hum and scream of their lightsabers barely audible above the wind howling in through the broken window.
"What do you require?" Ahsoka asked the mortal. He was one of her favored; had he not offered his life, she would have carried him to Valhalla upon his passing. It wouldn't do for him to die before he could tell her why he had offered so much.
The mortal gasped in pain, then with his last breath whispered "Stop the Sith Lord," and died.
His soul slammed into hers, intertwining and giving her his power. She remembered his name now, Obi-Wan, and mourned his passing. Ahsoka could not stop to grieve though. She had a Sith Lord to stop, and she was stronger than ever with Obi-Wan's soul bolstering hers.
The mortal who had been fighting the evil mortal screamed and fell to his knees, drawing her eyes, as he clutched at the stump of his arm.
"So, does the Padawan think she is capable of facing me?" the rotten mortal chuckled, staring at her from under his filthy robe. He was completely ignoring the mortal he had been fighting.
Ahsoka narrowed her eyes, angered by the insult. "You underestimate my skills at your own peril."
Before she could say anything else, the rotten mortal leapt at her, his crimson lightsaber crashing against her breastplate and sparking away.
She swung Mjolnir at his head in retaliation, but he flipped over her head, out of reach of her hammer.
Despite Mjolnir's extensive knowledge of battle, it had never been used against a lightsaber before and therefore had no experience against them. Ahsoka herself was skilled in a fight with and against a Force user, but she hadn't practiced using Mjolnir in combat before. The only thing that kept her from being grievously injured within the first thirty seconds of the fight was her armor.
The rotten mortal noticed that she was fumbling and used it to his advantage. His lightsaber found her uncovered joints and scored burns wherever it could. Ahsoka's own speed was the only thing that kept her from getting her limbs cut off at those spots.
Her own stubbornness would have kept her fighting the Sith until one of them dropped from exhaustion, but Obi-Wan's pragmatism advised her to take up a lightsaber rather than keep wielding Mjolnir. Anakin had taught her that it was usually best to follow Obi-Wan's advice, so Ahsoka threw Mjolnir at the Sith's face as soon as she had an opening.
While he was occupied with ducking out of the way, Ahsoka called a lightsaber to her. Its Adegan crystal hummed in a familiar manner once it flew into her hands, resonating with Obi-Wan's soul. The blade was a familiar blue when she ignited it, renewing her determination to see this mortal dead.
A moment later, the Sith's blade crashed against her own in a saber lock before he disengaged and whirled away. He spun around her, trying to find an opening in her defenses. If she had still been mortal, he would have found one, but she was not. As it was, she was hard pressed to keep ahead of him, circling around and trying to find an opening of her own.
The crash and hum of ignited lightsabers were the only sounds audible over the wind as it blew in through the window, pushing Ahsoka's cape out in front of her.
Neither of them were getting anywhere in trying to break each others' defenses. Ahsoka knew she would outlast him - the Sith was old, for all the Dark side was augmenting his strength, and she was a goddess- but the longer it took the greater the chance that the injured mortals would die. They had fought valiantly, but she would prefer to ferry the least amount of souls to Valhalla possible once she defeated the Sith. Ahsoka would have to create an opening.
She drew upon Obi-Wan's knowledge and Mjolnir's power and shattered the crystal inside the Sith's lightsaber.
Unfortunately, that had pulled the majority of her concentration from the fight, and he took the opportunity to stab her in the side before his lightsaber became useless.
"Die!" he snarled, throwing his ruined lightsaber to the side and using the Force to throw her out the broken window.
Even though gravity had snagged her in its grip and was pulling her to her doom, Ahsoka flung out her hand and summoned Mjolnir. Her hammer flew faster than she was falling, fast enough that she had only fallen a few stories before she reversed direction and flew back up.
Still, it was enough time for a storm to gather, thunder rumbling ominously as lightning crackled through the dark clouds. Ahsoka could feel it, the strength of the storm reflecting her mood, and as she reached the window the Sith had pushed her out of, a bolt of lightning reached down from the sky and struck Mjolnir.
Ahsoka paused long enough to stare into the Sith's shocked yellow eyes before she redirected the lightning at him, her power added to the lightning's to make sure it would be lethal.
When she landed, the air was full of the scent of electrified meat. Her footfalls and the wind were the only sounds as she checked to make sure the Sith was truly dead. As soon as she verified that he was, in fact, no longer among the living, Ahsoka could feel Obi-Wan's soul beginning to be absorbed into her own.
She set Mjolnir down on top of his chest to make sure that there would be no surprises from the body, then moved to tend to the Jedi. Shockingly, no one had died during her fight with the Sith, but there was little she could do to help them until the authorities arrived.
Whether it was gratitude or grief that drove her to sink to her knees next to Obi-Wan's body, Ahsoka didn't know. A proper Jedi would celebrate his passing into the Force, but she knew that he hadn't become one with the Force, that he might never do so, and it was her fault. She couldn't do anything to fix it, though, because she had no power over the dead. If she could bring him back, restore him to the full mortal life that should have been his, Ahsoka would have done it in a heartbeat.
Suddenly, a flash of inspiration struck her, inspired by a comment Mjolnir had made days ago. Hope surged in her heart, forcing out the grief, and she set to work, recreating Obi-Wan Kenobi into something new.
