Who Is Adina?

The team looks at Jack curiously at what they had just witnessed, Ianto crossing the hub to the rest of the team.

"Who is Adina? Princess Adina, the last of the Avalonian's and The Key To Worlds?" Ianto asks him now knowing that Jack was hiding something, something big.

"I think you should all sit down so I can explain this to you," Jack tells them and one by one the team moves over to the sofa area and sits down with Jack sitting down last and looking at his team.

"Phoenix is Adina or more to the point, Princess Adina. That is her title if her people still lived. Her planet is dead, destroyed but she was never meant for it. Phoenix was artificially created by the Time Lords, the Doctors race. When the Time Lord race was still young, war broke out on Avalonia, the war was amongst themselves and the King and Queen feared the end of Avalonia. Somehow and I say somehow because no-one knows how, not even the Doctor, Phoenix was given to the Time Lords to guard. She was given to them in the form of a DNA sample and were told that if the Time Lord race was ever under serious threat, they should create Adina, I mean Phoenix," Jack starts and he can feel their eyes all over him, suddenly feeling very uncomfortable.

"What happened for her to be here?" Owen asks him, very impatiently.

"Phoenix's DNA remained hidden by the Time Lords for century's, only the elders knowing of it. Then came word of the Daleks and that there were going to invade so the Avalonian DNA was removed and implanted into a human embryo with some Time Lord DNA, for only reasons they knew, I suppose they were following instructions but 13 weeks later, Phoenix was born," Jack explains further.

"Hang on a minute. Firstly, Phoenix is part human, part Time Lord but majority Avalonian and secondly, how was she born in 13 weeks?" Owen asks and the rest of the team seem to agree.

"Yes, she is part human, from her mother, part Time Lord from her father but mostly Avalonian from the DNA sample. As for the 13 weeks, like I found out the other day, Phoenix grew like any pregnancy she has. She grew 3 times faster than a usual baby so her mother was only pregnant for 13 weeks and not 39-40 weeks like normal human pregnancies, like Phoenix would have been with our son," Jack explains to Owen mostly.

"How wonder she is confused as to who she is. I would be with all that in me," Gwen replies.

"When Phoenix was born, she was a normal baby until she started growing and learning. By the time she was a year old, she was the size of a ten year old, she could speak at a higher year than she was, talk at a higher age, learn at a higher age and that was just the start. They found that she never got ill, if she hurt herself, she healed amazingly fast and the list just went on and on. There is a lot that I can't say about Phoenix, I wish I could but I just can't, it could change things in the future," Jack tells them and gives them a minute to let it sink in.

"So where does this The Key To Worlds come in and what did she mean about what she is capable of?" Ianto asks Jack and he knew it was coming and he wasn't looking forward to it.

"Her parents, her biological parents, the King and Queen of Avalonian, God and Goddess, told the Time Lord elders that Adina was precious and that one day, when she had come of age and was capable of handling it, she would be The Key To Worlds. After a lot of searching for answers and with help from the Doctor, Phoenix finally got the answer to that question. I can't go into this too deep but in very extreme circumstances, Phoenix has the ability to destroy a world or save it, which she chooses is entirely down to her," Jack tells them and then gets up and walks around.

"Did you just say that she has the ability to destroy worlds? Planets?" Ianto asks him and Jack takes a minute.

"Yes but only in very extreme circumstances were nothing else can be done. She didn't make the decision lightly and even sort advice from the Doctor first. Over the century's, Phoenix has destroyed two planets and one star, a star that threatened a planet," Jack tells them.

"I understand now when she said that the worst that had happened to us wasn't even in the same universe as what had happened to her. She is responsible for the death of thousands maybe even millions. That's why the Dark Avenger, helping people who can't help themselves. Penance for the lives she took. No wonder she doesn't want to let anyone close to her," Ianto replies understand more about what Phoenix had said to him in the corridor.

"That's why she buried all those bodies. That's why she is so alone, not just physically alone but mentally too. There is no-one else like her and she is afraid, afraid of every part of herself. Afraid to be human as human's love, hurt and loss and afraid of the goddess side of her because of what it is capable of," Toshiko tells the team.

"I was just thinking about why she is so keen to go after the entity and then it hit me. The entity and Adina, I mean Phoenix are both capable of the same thing, destroying planets but they are different in what makes them similar. Phoenix destroys planets because there is no other choice whatever the reasons behind it but the entity destroys planets seemingly for fun, killing millions of people, destroying so many different races and Phoenix doesn't agree with that. She never wanted to destroy those worlds but she had too and for something to come along and destroy planets for no good reason makes Phoenix agree and that is why she is going up against it. What are chances of survival Jack?" Owen asks him and they could see by the look on Jack's face that he was finding this very hard.

"Percentage wise, there is a 5 percent chance that she will survive this and come out the way she went in. There is maybe a 10 percent chance that she makes it out alive and she knows this. It takes too much out of her when she destroys a planet but to fight an entity that can fight back, it's a death sentence," he tells them with a tear running down his face as the realisation hits him that she was going to kill the entity ending her own life.

"We can't stop her can we?" Gwen asks him, a tear forming in the corner of her eye.

"If we stop her, we all die, Earth dies. She is sacrificing herself to save Earth, the people she loves the most. We need to help her in any way we can and that is why she has asked us to handle the foot soldiers. She needs to concentrate all her energy on the entity. We need help," Jack tells them and they all look at him.

"What are we going to do Jack?" Toshiko asks him as he paces.

"Ianto. Get Martha Jones on the phone. Tell her I need the Doctor. Toshiko, Owen and Gwen. Call anyone up that owes us a favour that can help us with this. U.N.I.T, the British Army, everyone. We are going to need troops on the ground. The more of us there are on the ground, the less Phoenix has to do. Anything to increase her chances," and no sooner had he said it, the team jumps into action.
