Trial By Fire: The Trial for Wisdom
Prologue
Luke couldn't believe it. It was finally over. The long battle against the Yuuzhan Vong is over. He looked around at his friends. They were all aboard the Errant Venture, heading back to Coruscant from the place of their final battle. He saw all of the people that he thought with, and the ones that he lost. He couldn't believe that they were all back. Every life that was taken, every planet that was taken over or destroyed, and even the droids that were lost came back. It was an amazing process to watch, and it only took a minute.
He looked beside him to see his wife, Mara, sleeping against his side. He thought that he almost lost her, when she had the disease. Now she was as healthy as ever. He was very happy to have regained all he had lost, and even receive something new. He looked in his arms and saw his son, Ben. He was sleeping peacefully. This was his other great gain. He now had a the family he wanted. When he and Mara watched Han and Leia's children grow, he really wanted to watch his own children grow up. He prepared not to have any, when it looked like that Mara might be stuck with the disease for the rest of her life. They didn't want to risk the child's life. So the took precautions to make sure that she wouldn't get pregnant. But something happened. One day Mara discovered that she was pregnant. She was scanning herself with the Force, when she found a thickening of cells in her uterus, and found her and Luke's life signature in it. They were very surprised. They came to the conclusion that the Force had a doing in conceiving Ben. There was no other explanation. He didn't know why, yet, but he planned to find out.
But for right now, he just wanted to enjoy the time with his family and friends. He had a knew life to look after, and with Mara it will be what he always dreamed. A real family.
