Discovered as a slave on Tatooine by Qui-Gon Jinn and Obi-Wan Kenobi, Anakin Skywalker had the potential to become one of the most powerful Jedi ever, and was believed by some to be the prophesied Chosen One who would bring balance to the Force. A hero of the Clone Wars, Anakin was caring and compassionate, but also had a fear of loss that would prove to be his downfall.
A legendary Jedi Master, Obi-Wan Kenobi was a noble man and gifted in the ways of the Force. He trained Anakin Skywalker, served as a general in the Republic Army during the Clone Wars, and guided Luke Skywalker as a mentor.
The Son was an embodiment of the dark side of the Force who dwelled on Mortis during the Clone Wars with his sister, the light-sider known as Daughter, and the powerful Force user known as Father, who tried to keep them in balance. Son sought to escape Mortis and wreak havoc in the galaxy, trying repeatedly to lure Anakin Skywalker to the dark side by changing form, possessing Ahsoka Tano and finally by showing Anakin a vision of the terrible acts he would commit. His efforts ultimately failed, culminating in his death along with those of Daughter and Father.
The Daughter of Mortis is a Force-wielder who aligns herself with the light side of the Force. An enigmatic being of tall stature who can transform into a griffin, she is the selfless counterpoint to her brother, the Son, who has allied himself with the dark side. Together they provide balance to the Force, a balance maintained and channeled through their Father.
