Sometime in the past

Mike and Kim were left at the door in a panic. Then Mike realized something, he had the same ability as the man who invented the door in the first place. He got the door open in time for a few people to enter before a hoard of arrows came whizzing through the trees. One hit Kim and another hit him. He thought they were goners until a familiar woman pulled them into the fortress and shut the door.

They could hear the turmoil outside, but knew that they would be safe in the fortress. Kindra smiled when she recognized the girl she had rescued, "I knew you would come back for us."

Mike was genuinely confused, and even more so when Kim gasped her last breath of air and suddenly turned into a happy healthy five year old. Kindra could see his confusion and decided to tell him what was going on.

"She is one of the ancients, we believe. As far as we know, she can't die. When she dies she is reborn. The only problem is, as time goes by she loses her memories that were once restored with every birth."

"Why is that?" Mike was feeling faint.

"I don't know, we figure she just blocks out all the horrible things she seen in her life."

"I see. I don't mean to cut you off, but I haven't got a lot of time left. I need to tell you some things."

"Go on." She put his head on her lap and listened intently.

"You need to warn them."

"Warn who?"

"The last generation. My generation. Terrible things are going to happen if you don't warn them."

"I see." he countenance grew dim

"No, you need to be the light. You're the only hope these kids will have. And your son, Jared. You need to start creating him as soon as possible. . ."

"What? I'm not even married."

"Please, I. . .I'm fading fast. Do this last thing for me, when I die cut off my arm so you will always be able to open this door."

It was the last thing he said. Kindra sat helplessly holding this stranger in her arms. Just then a man entered the room. "He's right. The first thing we need to do is try to save as many of this generation first."

--Flash Forward in time--
Kindra and the man (Jared's father) have been locked away for some time. Every once in a while they had tried to mentally make a baby. Their first few attempts failed and ended in still birth or miscarriages. The guards were starting to get wise to the situation, so Kindra developed a new power that manipulated the minds of the guards to see her starving and thin instead of pregnant.

This was difficult to maintain because they kept switching guards on her. Mike was one of the successful births (the others had been killed by the government as soon as they were discovered). Luckily, there was a new man in charge, and he decided he wanted to study Mike. So he raised him as his own. Mike was never told where he had come from or anything about magic.

Eventually, his adopted father discovered that Mike didn't have any powers and decided to train him to be a super soldier. To his dismay, Mike wasn't interested in killing people, but instead interested in the advances in technology.

Kim had been killed a few times, and as Kindra predicted suppressed most of her memories. The only memory she kept was her combat training. She was discovered by the government in the 70s, killed, then reborn. So they decided to keep a close eye on her and try to raise her as their own. She, of course, rebelled and ran away. Being naive, she didn't survive on the streets very long. Eventually in the 2004 she was reborn again, and managed to find an orphanage to live in.

Needless to say, the government was very excited to discover her in high school in the 2020. She was 16 and very persuadable. As soon as she graduated and turned 18 the government owned her.

Since technically there were two Kim's living in that window of time between when she arrived in the past and when she left the present, only one Kim retained her memories. Once she was out of that window of time, the original Kim came out of hiding. This Kim is completely different from the Kim that we are familiar with. She has never met any of the other characters but knows all about them, since she retains all of the memories that her other self forgot as well as her own.

Confusing? Yes. That's time travel for you.
