The Charmed Ones stood in the basement and watched amazed as Tara mastered each of her powers pretty quickly. She could levitate with ease, use her telekinesis and astral project, the only problem she was having was freezing and blowing things up. Which with Phoebe's new power was alright but Piper and Paige were still feeling the blow from losing their powers. The three sisters went upstairs and let Tara to practice with her freezing power alone. The Source flamed into the basement behind Tara; she spun and let out a quick scream as the Source threw a ball of low volt electricity that knocked Tara out. He picked her up in his arms and was just getting ready to flame out when the Charmed Ones came running down the steps. He smiled at them in triumph and flashed out.

Phoebe skidded to a stop. "Oh my god he has Tara. What're we gonna do?"
Piper yelled. "Leo, Leo damn it Leo."

He orbed in to the room looking at the sisters who were in varying degrees of panic. "What is it? What's wrong?"

Paige whirled around. "The Source has Tara."

Leo tried calming the sisters but wasn't having much luck when Cole walked into the room. After it was explained to him, he helped calm the sisters by telling them that the Source is not going to kill Tara. "Don't you see his plan? Tara is second only in power to you three if he can turn her evil he will have a great weapon against you."

Phoebe ran her hands over Tara's Book of Shadows and a premonition hit her. She saw Tara or what once was Tara. This new Tara had pure black hair and pure black eyes and she was getting ready to kill the Charmed Ones. As Phoebe came out of the premonition she collapsed in the chair. "I saw Tara with black hair and black eyes and she was getting ready to kill us."

Just as Piper was about to suggest they call in their mother and Prue the doorbell rang, Phoebe waved her hand at the others and went to answer it. Standing on the other side of the door was a smiling Buffy and Xander.

Phoebe was a bit shocked to see them. "Buffy, Xander what are you doing here?"

Well," Buffy said her smiling fading a bit, "we heard about your problems so we came to see if we could help plus we came to see Tara."

At the mention of Tara Phoebe broke and told Buffy and Xander everything. Xander stopped her. "Wait you saw Tara killing you and your sisters. Tara would never do that she is way to much an innocent."

"She was an innocent," Phoebe said, "the Source can and will corrupt her."

The Seer smiled to see Tara laid out on her alter it wouldn't take long to convert her to their side; she checked the dark energy coursing through Tara and smiled at the progress. Her plan was far different then the Sources, she wanted to rule the underworld and would use Tara to do so. The black woman's eyes clouded over as she stretched her power out and saw the Sources demise at the Warren Witches hands, no matter even with Tara's conversion back to the side of light, the Seers plan could still work

The Source flashed in and glided over to the Seer. "What did you see to make you smile so?"

"My liege I saw the prosperity of the dark side."

To herself she said under my control, to the Source she said. "With the turning of the Warren Witch I no longer see conflicting futures but one steady one that at the moment is still unclear."

Further talk was cut off by the moaning on the alter the Source and the Seer turned to see a dramatically different Tara, she had pure black hair and eyes that were black and seemed to have no depth

Buffy and Xander had sat and listened to everything the sisters told them, Patty and Prue had come back by now. It was Prue that addressed the issue. "So we combat the evil magick Tara will have with our white magick."

Buffy shook her head. "No in most cases that might work but Tara was a powerful witch before she found out her destiny, now add all the natural magick she had, to the new powers she got because she is the Warren Witch, and the evil powers the Source has given her, and you got one hell of a strong witch."

Piper stood up. "So what do we do?"

Buffy looked at Cole and back to the sisters. "You fight dark magick with dark magick."

Leo was on his feet instantly. "You can't be serious; you can't ask them to take a trip to the dark side now."

Buffy stood also. "I'm not, Tara may be one powerful dark witch but Willow has two times more natural magick then Tara ever did and she can call on the dark magicks."

Cole looked down and then up. "Then you risk losing them both."

"And you can't afford to lose Tara." Said a voice out of no where.

Paige had heard that voice only one before but knew who it was. "Grams?"

In a swirl of light the sisters grandmother appeared. "Hello my dears," she turned to Prue and Patty, "you two must leave now, do not argue with me. Just go."

The group watched as Patty and Prue left, then Grams spoke again. "It is most important that you get Tara back from the other side, it is her destiny to vanquish the Source."

Phoebe looked at her grandmother. "What do you mean it's her destiny?"

"The Charmed Ones were never meant to vanquish the Source; this is not your destiny. Everything Tara has done, every decision she has made has brought her here to this place and time. It is her destiny to vanquish the Source, the only one that is now powerful enough to do it."

The implication was there Piper and Paige no longer had their powers, Phoebe looked at Grams. "How do we do that, if the Source corrupted her, we would have to go to the underworld and I'm the only one with a power."

"You won't have to go to the underworld." Said a new voice, everyone turned and saw Tara a vastly different Tara standing there, her once blond hair was now pure black and her once kind, loving eyes radiated hate and evil.

Buffy and Xander were taken back by the look in Tara's eyes, Buffy stepped forward. "Tara what did they do to you."

She glanced at Buffy. "Made me strong, and showed me what I was missing being the good little witch." She turned to Phoebe dismissing Buffy, "You are the last with your power so we can do this the hard way or the easy way up to you."

Phoebe didn't answer but levitated and spun into a kick that sent Tara flying. When she stood, she actually sighed. "The hard way I guess." she shot fire from her hands toward the group who dodged the flames, Phoebe came up calling on her new power as she got ready to throw the bolt of electricity Buffy grabbed her arm.

"No if you do that it could kill her."

Tara glared at Buffy, where did this feeling of friendship come from. "Next time won't go so easy for you." and Tara shimmered out.

Buffy turned to Leo. "Go get Willow, she should be at the Magick Box," she turned to the others as Leo orbed out, "we will not use any lethal powers against Tara, if you do I will have Faith and Spike make you wish you were never born."

Grams looked at her granddaughters and her grandson-in-law. "My dears she is right, we need her good not dead. She is also right about Willow in this case the only way to win is to fight dark magick against dark magick.
