Issac Windflyer was trained by Dansa'olma Kan as a Jedi. His mom never was known, for his dad married over seventy-five women.
Birth and Childlife
Sandre Sidious was given birth by an unknown mother and Darth Sidious II. His mother, some say, lived on Coruscant and visited Darth every once in a while, and the people who that this believed he was born on the planet. At age seventeen Sandre went on a ship The Cosa Metis which was attacked by the rebellion and Dansa'olma Kan was in the group and took Sidious which had a concussion and a huge memory loss.
Being Raised by his "Uncle"
Luke took Sandre, unknowing his name calling him Issac, and said he was his uncle. When Luke brought Issac Windflyer to the doctor when he had the concussion he saw that Issac had the same DNA as The Emperor. Luke kept it as a secret only telling it to Dansa'olma. Luke told Dansa to teach Issac the light side of the Force.
Training of a Jedi
"Jedi are the guardians of peace in the galaxy.
Jedi use their powers to defend and protect, never to attack others.
Jedi respect all life, in any form.
Jedi serve others rather than ruling over them, for the good of the galaxy.
Jedi seek to improve themselves through knowledge and training,"
Issac saying the new Jedi Code.
Issac took only a day to learn about the force, because he already was taught it. It took five months to master the lightsaber though. It only took just a few weeks to fully learn the ways of a jedi. He learned how to teach younglings about the force and much later fight in battles.
After his fathers death in Episode IX Issac was told that he was the Emperor's son and he is the heir of the empire. As heir he then became emperor instantly. He then ruled the empire against the sith and for the jedi and the republic.
Issac married Bea Firebrand after thirteen years of knowing her. They were married until death having two kids Lizzie and Bolan Jaamos Windflyer.
Some say Issac never died. Others say Beatrice and him died together. His death is a mystery to the rest of the galaxy.
