Mahk shimmered into The Source's chambers. He walked a few paces, then kneeled in front of The Source. He took out the orb and held it out.

"Excellent." The Source said. "Prepare the altar."

Mahk nodded and stood. He took the orb to an altar that was behind The Source. He placed the orb down in the middle and waved his hand over it. In an instant and flash of light, Prue's body was laying on the altar.

Mahk immediately grabbed a copper bowl and went over to The Source. The Source raised his sword to Mahk's neck.

"The sacrifice you make furthers all demon kind." The Source said, then sliced the blade across, decapitating Mahk. The body immediately burst into flames and disappeared, but the copper bowl had at least a cup of blood in it.

A new demon raced forth and grabbed the bowl from the ground. He rushed over to Prue's body, then dipped his thumb into the blood.

"One for the side of good." The Source said. The demon streaked a line of blood on Prue's right cheek.

"One for the side of evil." The Source said. The demon streaked a line of blood on Prue's left cheek.

"One for all eternity and what the Fates may bring." The Source said. The demon streaked a line of blood on Prue's forehead.

The demon dropped the bowl of blood, then a dagger appeared in his clawed hand.

"One for sacrifice." The Source said. The demon plunged the dagger through his heart and screamed. He removed the dagger then put his thumb to the wound. He pressed in to get blood on his thumb, then waited.

"Two for resurrection." The Source said. The demon streaked two lines of blood on Prue's eyelids, then fell to his knees and exploded in flames.

The Source waited. If all went to plan, she would awaken with the essence of demon inside her. The most powerful Charmed One would be at his side. He would, however, only have her for one year. He had to make that year count.

The Source watched. Her eyes shot open and she sat up. She looked directly at him, then she screamed and dove at him. He simply raised his hand and she crumpled to the ground. She got to her feet in seconds, seething with rage.

"I knew your first instinct would be to attack me." The Source said. "The side of good still holds you strong, I expect."

Prue said nothing. She stood, breathing heavily, just staring at the face she could not see. The Source could almost see the anger spilling out of her.

"Well," He continued. "Your instincts will change. You will join me."

"I will never join you." She said, her voice steady and full of rage.

"I expected you would say that." The Source said. "That is why I have a proposition for you."

"Speak." Prue demanded. The Source narrowed his eyes, not that she could see.

"You will stay with me for one year and do my bidding." He said. "Then, after your year of service, you may return to your sisters."

"I'll just return to them now." Prue said.

"You cannot." The Source said. "The side of evil has brought you back from death and you will serve it. You will serve me."

"And if I don't?"

"You must." The Source told her. "If you do not willingly serve the side of evil for one year, the essence of demon inside of you will take over your body completely and you will turn into a full demon. However, if you willingly serve, the essence stays just that. An essence. You will remain your usual self then have the opportunity to turn back."

Prue thought it over. One year of being evil. Willingly evil. But she would never do that...but, then again, if she didn't, she would become a demon. But, after her year of service, she would have enough information to be able to defeat The Source.

Prue sighed. Her decision would be made; only to save her sisters.

"I will serve." Prue said. "But only on the condition that my family is never harmed and I don't have to kill anyone."

"Done." The Source replied.

There were flashes of lightening, then a chunky, black bracelet (like the ones genies were forced to wear) appeared on Prue's right wrist.
