- "I can't even lock down where in the galaxy we are or if we're even in our own galaxy."
- ―Obi-Wan Kenobi, on landing on Mortis.
After intercepting a 2000-year-old distress message, the Jedi High Council sent Jedi Master Obi-Wan Kenobi, Jedi Knight Anakin Skywalker and his Padawan Ahsoka Tano to investigate. Fearing a Separatist trap, the three Jedi were to to meet with clone captain CT-7567, nicknamed "Rex," in a heavily armed Venator-class Star Destroyer. But when the Jedi's Eta-class shuttle and the destroyer met at the rendezvous point, they couldn't see each other. The shuttle was then suddenly pulled into a monolith, causing the Jedi to black out.
When the Jedi woke up, they found themselves on a strange planet which was strong in the Force. A woman named Daughter met them and continuously asked if Skywalker was the Chosen One. When the Daughter attempted to take them to her father, a rockslide separated them. Skywalker decided to follow the Daughter while Kenobi and Tano headed back to the ship, however when they reached the spot where the ship was, they saw it was gone. Night was descending upon the planet and the Jedi noticed that all the plants were dying. They then met a humanoid named Son. Tano and Kenobi ignited their lightsaber but the Son simply deactivated them using the Force, forcing Kenobi to believe that he was Sith. The Son replied that he was and was not Sith. He then told Kenobi and Tano that it would be wise to seek refuge in a cave. Meanwhile, Skywalker snuck into a monastery and met with a man named Father. The Father offered Skywalker a room in the monastery for the night.
Meeting the past and futureEdit
Meanwhile, back in the cave, Kenobi and Tano were fast asleep. Kenobi awoke to find the spirit of Qui-Gon Jinn, Kenobi's deceased master. Jinn asked Kenobi if he had trained Skywalker as he had asked. At first Kenobi reacted in shock by igniting his lightsaber, but withdrew upon realization. Jinn then explained that the inhabitants of Mortis, like him, believed Skywalker to be the Chosen One.
In the monastery, the Son visited Skywalker disguised as his deceased mother, Shmi Skywalker Lars. After Skywalker confessed his sins, which included killing so many to avenge her death and his forbidden marriage to Padmé Amidala, Shmi told him that Amidala did not represent his true destiny. She then disappeared but not before briefly showing Son's gargoyle form.
In the cave, Tano was fast asleep until she was woken by a voice which asked her if she was happy. When Tano got up, a vision of her future self appeared behind the fire. The vision warned her that Skywalker was planting the seeds of the dark side in her mind and that if she was to reach her potential, she had to leave Mortis. Tano's future self disappeared in a storm of fire.
- "The Chosen One is a myth."
"Is it? I should very much like to know. Why don't we find out together? Pass one test and I shall know the truth and you and your friends may leave."
- ―Anakin Skywalker and Father.
In the monastery, Skywalker approached the Father with his lightsaber drawn. Skywalker accused him of being a Sith Lord because of his powers. After shutting off his lightsaber with a touch, the Father explained the special Force Powers that he, Son and Daughter possessed. He explained that they were anchorites. They had become so strong with the Force that they were forced to retreat to Mortis so they can keep their Force powers in balance. He had to maintain a balance between the Daughter, who was aligned with the light side of the Force, and the Son, who was drifting closer to the dark side of the Force.
The Father called Skywalker to Mortis, believing he was the Chosen One. He decided to set up a test for Skywalker to prove this theory. The Father promised that if Skywalker passed, he and his friends would be allowed to leave. The Father commanded the Son and the Daughter (in their animal forms) to capture Tano and Kenobi the next morning and bring them to the monastery. Skywalker and Father were waiting for them in the courtyard of the monastery. The Daughter, holding Kenobi, landed on one side while the Son, holding Tano, landed on the other. The test was to see which one Skywalker would save but as he surmised, it was impossible to save both.
At first Skywalker refused, but Father denied it, saying only Skywalker can tame his children. Using the Force of the planet, Skywalker lifted the Daughter and Son off the ground and forced them to release the two Jedi. He then brought them to their knees, while simultaneously transforming them to their humanoid forms. During the test, the time of day changed from day to night, and then back to day. The Father was then convinced that Skywalker had to replace him there on Mortis to maintain the balance between Light and Dark. Skywalker however refused to take the Father's place. The Father, knowing that it must be Skywalker's choice, let him and his friends go to their ship and leave the planet.
As the ship was leaving orbit, the Son appeared to Skywalker in his dream, first as a reflection of Skywalker, then becoming his true self. He attempted to seduce Anakin to the dark side but Anakin resisted and after a while, woke up. But not long after, the Son infiltrated the ship and kidnapped Ahsoka. He then flew out with her, forcing Anakin and Obi-Wan to chase him in full pursuit. But the Son managed to lose them and took Ahsoka to a large tower. However, Anakin and Obi-Wan crashed their ship while trying to avoid a bunch of rocks. Although both the Jedi survived, their ship was damaged. Anakin left to find Ahsoka but Obi-Wan warned him of the possible danger and decided to take Father's help but Anakin refused to wait and decided to move on to the tower, leaving Kenobi with the ship. At the tower, the Son transformed into a small blue creature and went over to Ahsoka whom he had tied to the wall with chains. He told Ahsoka that there is no escape but Ahsoka responded that she was a Jedi and that she will escape. The Son then released her from her binds but then bit her on the wrist, knocking Ahsoka into unconsciousness. The Son then transformed back into himself and watched as Ahsoka slowly moved to the dark side. He then joined Father and Daughter back at the monastery.
Meanwhile, Kenobi decided to follow his own plan and went to the monastery to seek Father's help. At the monastery, the Son began to grow impatient, waiting for his Father's death, especially after the Father threatened to contain his Son if he did not control his power. The Son reacted angrily by shocking his Father and then flying away, right past the bewildered Kenobi. The Father rolled down the stairs of the Monastery and stopped near Kenobi. The Daughter immediately rushed to her Father's aid who was unconscious and with Kenobi's help, laid him back in the Monastery. Daughter felt that the Son had to be stopped once and for all. Leaving Father in the monastery, she took Kenobi to an altar which held the Dagger of Mortis, a weapon capable of killing powerful Force-wielders such as Son, Father and Daughter.
Meanwhile, Anakin arrived at the Son's cathedral and found Ahsoka, not knowing that she had been poisoned by the dark side. Ahsoka told Skywalker that if he did not join the Son, he will kill her. But when Skywalker refused, she drew out her lightsaber saying that he will be forced to kill her. She then attacked Skywalker though Skywalker, not wanting to harm her, remained in a defensive position. The Son was watching the battle from his tower when he was confronted by Daughter and Kenobi. But after Kenobi rushed off to help Skywalker, only the Daughter was left with the Son.
While Kenobi and Skywalker dueled Ahsoka, Daughter rushed to help them by was stopped by Son who lifted her with the Force and threw her a couple of distances away. The Daughter retaliated by doing the same. Back at the monastery, the Father awoke and flew towards the tower.
At the tower, Kenobi suggested to free Ahsoka using the dagger. Meanwhile, inside the tower, Son and Daughter continued hurling Force Powers at each other either in the form of levitation or lightning, both cancelling each other's power out. It was not until the sudden appearance of Father that the two stopped before Father hurtled them out through the window with the Force. The Jedi ceased their duel when the Son and Daughter landed in the courtyard, Father following close behind. In anger, the Son blasted the weakened Father with lightning but the Father blocked it, although he began to grow weaker. The Son proved too strong for him and the Father fell back, only to be shocked by another round of lightning before Kenobi finally decided to use the dagger. However, Ahsoka caught the dagger and turned it over to the Son, who snuffled the life force out of her by tapping her on the forehead. When Son attempted to kill Father, Daughter got in the way and was killed instead. With the Daughter dead, the balance was broken and the Sith were to gain power as the Son, who had fled, was still alive. Father grieved his daughter's death but before dying, Daughter gestured towards the dead Ahsoka, trying to say that she can use her last bit of strength to save Ahsoka. Anakin came forth and used himself as a bridge to transfer life from Daughter to Ahsoka. With Daughter dead, Ahsoka woke up, unaware of what had happened to her for the past few hours. The Father told them all to leave this planet before the Son could take their ship out. The trio then left the mournful Father with his dead daughter.
The Son tempts AnakinEdit
While Ahsoka attempts to repair the damaged shuttle for their escape from Mortis, Anakin and Obi-Wan contemplate whether this is the right course of action, with Son, corrupted by the Dark Side, still being at large. Anakin decides to return to Father Mortis and seek his help since he has doubts that Son can be held prisoner on this planet permanently, and meets with him outside the crypt where Father has just buried Daughter, the Dagger of Mortis laid upon her breast. Father is now determined to eliminate Son and the danger he poses to the universe, but refuses to accept Anakin’s offer of aid, since Son would easily use Anakin’s power to tip the balance of the Force, wreaking havoc in the galaxy. He tells Anakin that the Force will now decide over their fates and to look inside himself for the answer for what is to be done.
When he leaves the crypt, Anakin encounters a ghostly apparition of his first Jedi mentor, Qui-Gon Jinn. Still doubtful about what to do with Son, Anakin seeks Qui-Gon’s advice, but just like Father, Qui-Gon advises him to look into himself for the true answer, and tells him to go to a certain place, the Well of the Dark Side, to face his most personal challenge. In the meantime, Obi-Wan prepares to look for Anakin when he is met by Father, who tells him of Anakin’s destination but tells him not to interfere. Obi-Wan protests, however, and departs for the Well.
Anakin descends into the Well, which lies hidden in the fiery bowels of Mortis, where he is met by Son. Son attempts to draw him to his side by revealing glimpses of Anakin’s future. Fearful, Anakin refuses to confront the images and is overwhelmed by anguish. Son offers to help him change his future and prevent what Anakin has seen, and Anakin chooses to go with him. When Obi-Wan arrives a short time later, he finds Anakin poisoned by the dark side and in Son’s company, who then depart, leaving Obi-Wan behind. Obi-Wan contacts Ahsoka, instructing her to disable the shuttle (just right after she has managed to repair it), but before she can go about the task, Anakin arrives. Just in time, Ahsoka manages to sabotage the power systems, get away and recover Obi-Wan. Worried that the two will join forces with Father, Son departs to prevent this, penetrates his sister’s tomb and recovers the Dagger.
Left alone, Anakin is confronted and questioned by Father, who erases Anakin’s memory of his future revealed to break the hold of the Dark Side on him, and the two are rejoined by Obi-Wan and Ahsoka at the monastery. Son arrives soon afterwards, and Father pleads with him one last time to let go of his plans. When Son refuses to give up, Anakin attacks him, shortly followed by his friends, but Son proves too powerful for them. In order to strip his son off the Force which he has bestowed upon him, Father takes the Dagger and turns it upon himself. Shaken by remorse, Son recovers and makes peace with his father, just before he is run through by Anakin’s lightsaber. With his dying breath, Father proclaims Anakin the Chosen One since he has brought balance back to this world, but warns him to beware his inner self or else he will bring doom to the galaxy.
With the death of Father the Force which has permeated Mortis dissipates, and a falling crystal shatters on the tip of the monastery’s tower, enveloping the three Jedi with a blinding flash. When they come to, they find themselves back in space inside the shuttle and being contacted by Rex. They are confused to learn that only a moment has passed since they lost contact with their cruiser, but recover sufficiently enough to complete their rendezvous.
After the events of the mission, Obi-Wan later filed a report on the events of the mission upon returning to Coruscant.
The Father's warning to Anakin Skywalker regarding his refusal to stay eventually came to pass when it was revealed that, thanks in part to the Ones' death, Abeloth, upon being inadvertently freed by Jacen Solo's actions as Darth Caedus, was free to commence her rampage against the Galaxy without worrying about the Ones stopping her.
Afterwards, Anakin's son, Luke Skywalker, acting on knowledge learned from Obi-Wan's report on the mission as well as Yoda's explanation of the mission, later sent a Jedi task force to locate the Mortis Monolith to retrieve the Mortis Dagger from Mortis so they'd have insurance in case Abeloth returns after recent evidence suggested that Abeloth's defeat in Luke and Darth Krayt's duel did not result in her absolute destruction.
