Leia Windu, family named Kenobi, originally Leilady Kunegunda Kenobi-Windu XIII, was a human female born in the town of Kywalker on Dantooine, the sister of Padme Kenobi and Obi-Wan Kenobi and Shmi Skywalker's childhood friend.
Before the start of the Clone Wars, Leia had born her first baby, named Stanislav, who would later become known as Snoke. During the war, the woman got married to Mace Windu, taking his last name as her own one from then, and after 4 ABY she got married again but to Luke Skywalker. However, she cheat on him with Lando Carlissian and, accidentally, gave birth to Celina Carlissian. Due to thinking they would not be great parents, the spouses chose to make such a step as freezing her in carbonite. Some time later Leia's next lover became Chewbacca, with whom the female also had a child, and that time it was a boy named Lowbacca. Willing to keep his existence secretly, the human and the Wookiee handed him over to Katarzyna, who then sent him to Chewbacca's sister to bring up the baby to be her own one.
In 10 ABY Leia committed to Jar Jar Binks and some time later, together with him and her old friend Shmi, got into the the forefront of Jar Jars's Empire, founded by them before. Finally, due to a few complications within the country's command, Leia was killed by the Gungan during the Attack on Ranttoine, but one year later the woman was revived by Ben Solo and Lanever Villecham. After that she once more came back to Luke, being sure that she would stay with him for good.
Within next years Leia took part in searching the galaxy for the First Lightsaber. In order to get it, other six ancient weapons were needed to be found so they would work as the key. Having gotten them all, together with her friend she went to Endor. Finally, however, the artifact was taken over by a mystery user of the Force. After those events Luke decided to split her wife up to follow the Jedi Code. For it to come true, he also taken Ben Solo as his apprentice. The female, then, came back to Lando Carlissian, with whom she moved to the planet of Jakku, where they both chose to unfreeze their daughter and sell her, having changed her name to "Rey".
In 21 ABY Leia went to Kashyyyk to see Chewbacca once more. When they had both been founded by their son Lowbacca, they managed to explain him why they had left him before years. Then, the mystery Force user landed on the planet and he turned out to be Mace Windu. During the duel the old Jedi killed Low and, defending himself, accidentally hurt Leia. She, though, once more gave him her love to save Ben Solo, who was present there as they were. Due to having lost too much of her blood, Leia finally died in the arms of her first loved one.
