Chapter Summaries

Kahn explained his origins to Team Avatar, who accepted him as a friend, then began teaching Aang Firebending by showing him how to apply restrained Airbending to controlling flames. Aang quickly understood the idea, and Kahn left him to practice with a small flame.

• Kahn told Aang, Katara, Sokka, and Toph that he came from a parallel world, and Sokka defended him as an ally.
• Aang and Katara agreed that Kahn was their friend, while Toph complained that their conversation was keeping her awake.
• Kahn asked Aang to restrain the airflow around his body, and Aang learned to guide it without creating a breeze.
• Aang realized that controlling fire could feel like controlling the air, and Kahn praised his progress.
• Kahn lit a small flame on his fingertip and told Aang to practice controlling it with the same restraint.

Aang overcame his fear and began learning to control fire under Kahn’s guidance. At Palm Oasis in the Mist, Kahn revealed that he had come to find Wan Zhi Tang’s Mysterious Library and search for records of ancient Firebending, which the group planned to seek out after resting.

• Kahn startled Aang into throwing a fireball, then easily dispersed it and helped Aang gain confidence controlling flames.
• Aang thanked Kahn for his lessons, and Kahn suggested visiting Palm Oasis in the Mist to aid Aang’s Firebending training.
• The group arrived to find the oasis and its ice spring badly diminished, then rested and drank chilled fruit juice.
• Kahn told the group he had come to find Wan Zhi Tang’s Mysterious Library, said to hold knowledge gathered by the god Wan Shi Tong and his messengers.
• Kahn explained that modern Firebending had been altered for war and that he hoped the library contained records of its ancient form.
• Kahn said he had already located the library with Mind’s Eye, and the group agreed to rest a little longer before setting off.

Aang and his companions defeated desert bandits who tried to steal Appa, then followed Kahn’s directions to the Deity’s library. Inside, they encountered the Deity, a giant owl, who threatened to turn them into specimens.

• Aang and his companions confronted Sandbenders who tried to take Appa, and Toph buried several attackers in the sand.
• Kahn joined Aang and Katara in defeating the bandits, then robbed them and destroyed their clothes and sand-sailers.
• The group rode Appa to the Deity’s library, where Toph stayed outside while Kahn, Aang, Katara, and Sokka entered through a window.
• Kahn told the others to let him speak to the Deity and reminded Aang of the Avatar’s role as a bridge between humans and Deities.
• A giant black owl appeared inside the library and ordered the humans to leave, threatening to make them anthropological specimens.

Kahn, Aang, and their companions gained access to Wan Shi Tong’s library and found an ancient Firebending scroll. Wan Shi Tong revealed that Admiral Zhao had burned the library’s Fire Nation records, then learned Zhao had been taken by Tui, leaving the group to depart with their search complete.

• Wan Shi Tong challenged the group’s motives, but let them into the library after Kahn apologized and explained they sought ancient Firebending rather than knowledge to destroy others.
• The group donated knowledge, and Wan Shi Tong especially valued Kahn’s training notes and guided them to the library’s collections.
• They discovered the Fire Nation section had been burned, and Kahn and the others reacted with anger and dismay.
• Kahn found the ancient Firebending scroll called the “Dancing Dragon,” while Aang and Katara studied scrolls from their own bending arts.
• Wan Shi Tong showed Kahn and Aang a vision identifying Admiral Zhao as the one who burned the records, then learned Zhao had been taken by Tui and flew away laughing.
• Kahn and the others left the library, with their search for ancient Firebending fulfilled.

After the group learned the date of the next solar eclipse, Kahn revealed that he had already killed the Ozai in his own world and argued that defeating this world’s Ozai would be straightforward. He warned Aang that ending the war would also require navigating succession, reparations, territorial disputes, and other political problems, and the group continued toward Omashu to seek the Earth Kingdom’s king.

• The group obtained the Dancing Dragon technique and learned when the next solar eclipse would occur, prompting Sokka to propose attacking during it.
• Kahn dismissed the eclipse plan as unnecessary and described a night infiltration of the Imperial Capital to kill Ozai.
• When Sokka asked how Kahn knew about Ozai and the palace’s secret passage, Kahn revealed that he had already killed the Ozai in his world.
• Kahn assured Toph that his plan could work, but told Aang that killing Ozai would only begin the difficult political work of restoring peace.
• Sokka suggested meeting the Earth Kingdom’s king, and Aang agreed to continue with their original plan as Kahn looked forward to seeing Omashu.

Kahn proposed that Earthbenders could control metal, and Toph quickly developed metalbending by sensing the earth element within a copper coin. When the group spotted a massive Fire Nation drilling machine heading for Omashu, Kahn urged Toph to use it as metalbending’s debut.

• Kahn discussed metalbending with Toph, arguing that metal came from the earth and that her talent could make it possible.
• Toph experimented with a copper coin and, inspired by Katara’s explanation of Swamp Waterbending, learned to control the earth element within the metal.
• Toph reshaped the coin into a ball and then a sheet, declaring herself the strongest Earthbender.
• Sokka spotted a huge Fire Nation machine carrying a drill, and Kahn identified it as a weapon designed to breach Omashu’s walls.
• Kahn suggested that Toph demonstrate metalbending against the machine, and Toph eagerly agreed.

Kahn and his companions destroyed the Fire Nation’s drill and reached Omashu, where a suspicious palace guide delayed their meeting with the king. The chapter ended with Kahn warning the others that Judy might have been brainwashed.

• Toph tore into the drill and wrecked its machinery, leaving the Fire Nation commander to face Azula’s threats.
• Kahn and his companions flew toward Omashu on Appa, and Azula spotted them as they departed.
• Aang announced that he was the Avatar, and the group entered Omashu and traveled through its agricultural and residential districts.
• Judy introduced herself as their palace-appointed guide and said meeting the king could take two to three months.
• Kahn stopped Sokka from arguing with Judy, asked to rest, and later told the group he suspected she had been brainwashed.

Kahn and Team Avatar suspected Judy had been brainwashed to stop them from meeting the emperor, so they decided to explore Omashu and gather information while staying cautious. In a teahouse, Kahn unexpectedly encountered Zuko and Iroh working there.

• Kahn explained that Judy’s rehearsed behavior and reactions to questions about the war suggested she had been brainwashed, though he did not know why.
• Sokka realized Judy had said she was sent by “the higher-ups,” not necessarily by the emperor, and the group agreed to investigate Omashu carefully.
• Katara suggested they enjoy the city while quietly gathering information, and the group planned to split up so Judy could not watch them all.
• The next morning, Katara and Toph went out together with Judy following them, while Kahn explored Omashu alone.
• Kahn followed a passerby’s recommendation to a popular teahouse and discovered Zuko and Iroh working there.

Kahn visited Iroh and Zuko’s teahouse in Omashu and revealed that he was Tate’s son from another world, where Iroh had adopted him. Iroh accepted Kahn’s unbelievable story, and they began reconnecting across the worlds.

• Kahn drank tea and watched Iroh and Zuko run their teahouse, feeling unexpectedly at home.
• Zuko worried that two customers had recognized him, while Iroh guessed that Jin was interested in Zuko; Jin introduced herself and spoke with him.
• Iroh told Kahn that he seemed familiar, and Kahn asked whether he reminded Iroh of his father, Tate.
• Iroh recalled Tate’s death and learned from Kahn that, in this world, Tate’s wife and child had died after his battle loss.
• Kahn explained that he was the child who had died in this world but survived in another, where Iroh adopted him; Iroh trusted him and welcomed the extraordinary revelation.

Kahn told Zuko where Ershu might be and urged him to seek the Avatar’s help in restoring her memories. He confronted Zuko about his pursuit of the Avatar, leaving Zuko shaken and questioning what he should do.

• Zuko and Iroh brought Kahn to their home in Omashu after Kahn offered information about Ershu.
• Kahn said Ershu was likely in Rah Town and explained that finding the Mother of Faces could restore her memories.
• Kahn suggested that Zuko ask the Avatar for help, but Zuko admitted he still believed capturing the Avatar was his mission.
• Kahn challenged Zuko to face Ozai’s responsibility for his exile, scar, and separation from Ershu, leaving Zuko confused and distressed.
• Kahn ended the conversation without giving Zuko an answer, and Iroh thanked him for confronting Zuko.

Kahn and the others connected Omashu’s strange behavior to the Dai Li and planned to investigate before sneaking into the king’s banquet. Kahn then returned to Iroh, found Zuko ill from inner turmoil, and agreed to tell Iroh more about himself before asking about the Dai Li and the White Lotus Society.

• Katara and Toph reported finding two palace maids named Judy who shared identical mannerisms, leading Toph to suspect large-scale brainwashing.
• Sokka told the group that the Dai Li arrested people who discussed the war and returned them seemingly changed, with their memories of the war erased.
• Kahn concluded that someone may have seized control of the Dai Li and was keeping the king from learning about the war.
• Aang suggested sneaking into the king’s upcoming banquet, and the group split up to search for the brainwashing site and the mastermind’s identity.
• Kahn visited Iroh again and learned that Zuko was bedridden with a fever after struggling with the ideas Kahn had raised.
• Iroh asked Kahn to be open about himself before answering his questions about the Dai Li and the White Lotus Society, and Kahn agreed.

Kahn told Iroh about his parallel world and learned that Grand Secretariat Chang Feng controlled the Dai Li and that Reformation Lake was where they brainwashed people. Iroh revealed the Ancient Sun Warriors were still alive and sheltered two dragons, while Kahn disclosed that Ozai had murdered the old Fire Lord; Iroh ended by questioning Kahn about his connection to Azula.

• Kahn explained his origins and his work teaching Firebending to the Avatar, and Zuko said he no longer wanted to capture the Avatar.
• Iroh identified Chang Feng as the Dai Li's mastermind and said their brainwashing took place inside Reformation Lake, while explaining why the White Lotus Society would not interfere.
• Kahn gave Iroh a Dancing Dragon scroll, and Iroh revealed that the Ancient Sun Warriors still lived and protected the world's last two dragons.
• Kahn learned that Iroh had secretly escorted the dragons to the Sun Warriors and said he wanted to visit them.
• Kahn told Iroh that Ozai had killed the old Fire Lord and altered his final decree, then let slip that Azula had told him secrets, prompting Iroh to question their relationship.

Kahn brought Iroh and Zuko to meet Aang and the others before their plan against the Dai Li, and Zuko explained his past to earn their trust. After learning that Long Feng controlled the Dai Li and concealed the war from Omashu’s king, the group prepared to disrupt the banquet.

• Aang and Toph confirmed that the Dai Li were brainwashing people beneath Reformation Lake and saw palace maids being processed there.
• Kahn introduced Iroh and Zuko, who asked Aang and the others for a chance to make amends and work together.
• Zuko told the group how Ozai scarred and banished him, and Aang revealed that Zuko had once rescued him from Admiral Zhao.
• Aang and the others accepted Iroh and Zuko as allies after hearing their stories.
• The group learned that Long Feng controlled the Dai Li and Omashu but had not taken control of the king’s armies outside the city.
• Aang and the others set out to disrupt the banquet.

Kahn and Team Avatar crashed the Earth King's banquet and fought the Dai Li, then confronted Chang Feng about his plot. With the palace guards already defeated, Chang Feng's attempt to summon reinforcements failed, leaving the Earth King to hear their claims.

• Chang Feng grew uneasy when the two men assigned to watch the Avatar failed to report, so he ordered the Dai Li to tighten security.
• Appa burst into the banquet hall carrying Team Avatar, and Chang Feng called them assassins while trying to evacuate the Earth King.
• Aang raised earthen walls to block the Dai Li's Silent Fist attacks, and Kahn, Zuko, Iroh, and Aang defeated the attackers.
• Aang told the Earth King that Chang Feng was keeping him in the dark, and the group put down their weapons at the king's request.
• Chang Feng ordered his forces to seize Team Avatar, but Kahn revealed that they had already cleared out the palace guards.

Aang and his friends exposed Chang Feng’s deception and showed the Earth King the truth about the war and the Dai Li’s brainwashing. With Omashu’s leadership restored, the group planned their next steps, leaving Kahn, Zuko, and Iroh behind to coordinate with the Earth Kingdom army.

• Aang told the Earth King about the war and the Dai Li’s brainwashing, but Chang Feng denied the accusations and the king proposed investigating the next day.
• Kahn chi-blocked the Earth King and Chang Feng, carried them to Appa, and took them to Reformation Lake, where Katara and Toph guarded the captured Dai Li agents.
• Aang and Toph showed the Earth King the brainwashing site, and he accused Chang Feng of treason before visiting Omashu’s outer wall and confirming the war.
• The Earth King thanked Aang and his friends, while Chang Feng was imprisoned and General Hao’s search of his home uncovered a letter for Toph and a report about Hakoda defending Chameleon Bay.
• Aang planned to visit the Eastern Air Temple to train with Guru Pathik, while Kahn, Zuko, and Iroh agreed to stay in Omashu and coordinate with the Earth Kingdom army.

After leaving the Earth King to decide the Dai Li’s fate, Kahn watched Iroh coordinate the eclipse campaign with the Five-Man Council and later welcomed Toph back to Omashu. His quiet respite ended when the Earth King summoned him.

• The Earth King insisted on keeping the Dai Li under his direct command, and Kahn left the Royal Palace rather than argue further.
• Iroh and Zuko met with the Five-Man Council, and Iroh helped the generals plan their campaign against the Fire Nation around the solar eclipse.
• Kahn returned to his lodgings and practiced his Bending while Iroh and Zuko stayed busy.
• Toph returned to Omashu after discovering that her Earthbending teacher and an underground gambling den host had lured her away; she trapped them in an iron cage.
• Kahn spent his free time sparring with Toph and visiting Iroh and the others until the Earth King summoned him.

Azula captured Kahn and threatened to have the Dai Li brainwash him, but Kahn revealed that he had prepared an ambush with Toph. They overpowered Azula and her companions, and Kahn left the palace with Toph and the Earth King as Azula screamed after him.

• Azula used the Dai Li to restrain Kahn and revealed that she planned to have him brainwashed into her obedient servant.
• Kahn learned that Azula had gained temporary control of the Dai Li through an agreement with someone he suspected was Chang Feng.
• Kahn unleashed a disorienting shout with Spiritbending and called for Toph, who emerged from underground and pinned Azula, her companions, and the Dai Li to the ceiling with stone pillars.
• The Earth King ordered the guards to arrest the rebels, but the guards did not respond because Azula's group had already dealt with them.
• Kahn and Toph left to have the captives locked up, and the Earth King hurried after them while Azula screamed Kahn's name.

After the Earth King dissolved the Dai Li, Zuko and Iroh returned and Zuko persuaded Mai and Ty Lee to join their side, though both feared Azula and refused to oppose her if she escaped. Zuko failed to reach Azula in prison, while Kahn discovered that only three of his Seven Chakra Gates remained blocked; Toph then welcomed Butterfly and Katara back.

• The Earth King scattered the Dai Li among the Five-Man Council's units and dissolved the organization.
• Zuko spoke with Mai and Ty Lee, who joined his side, and he and Mai made their relationship official.
• Mai and Ty Lee warned that they would not oppose Azula if she escaped, explaining that Azula had threatened them and Mai's father.
• Zuko tried to reason with Azula in her heavily shackled cell, but she mocked him and he left in anger.
• Kahn examined his Seven Chakra Gates and found that fear, lies, and attachment to the mortal world still blocked three of them.
• Toph joyfully greeted Butterfly and Katara when they returned.

Aang returned from training without mastering the Avatar State and secretly told Kahn that he had fled because Guru Pathik said he must give up his feelings for Katara to open his final Chakra Gate. Kahn asked whether Guru Pathik had told him to give up those feelings or let them go.

• Kahn and Toph told the group how Azula infiltrated the Royal Palace, the Dai Li rebelled, and Azula and her allies were captured or turned to their side.
• Mai said the real Kyoshi Warriors had probably been sent to a Fire Nation prison, and Sokka angrily stormed out over Suki's imprisonment.
• Kahn changed the subject, and Katara recounted how she and Sokka fought at Chameleon Bay and earned Hakoda's and their tribespeople's respect.
• After Zuko, Iroh, Mai, and the others left, Aang privately confessed to Kahn that he had secretly left his training because he could not master the Avatar State.
• Aang revealed that he loved Katara and could not give up those feelings to open his final Chakra Gate, so Kahn asked whether Guru Pathik had told him to give them up or let them go.

Kahn explained to Aang that the final chakra was blocked by obsession, not love itself, and that Aang had to truly let go of his fixation on Katara. Aang decided to return to Guru Pathik for help, while Kahn admitted he still had a long way to go in opening his own chakras.

• Kahn told Aang that Guru Pathik’s warning about earthly attachments could be understood as a need to let go of obsession, rather than abandon someone he loved.
• Kahn asked Aang how he would respond if Katara loved someone else, and Aang chose to wish her well and move on.
• Aang questioned why his final chakra remained blocked, and Kahn explained that he had to face the issue calmly or use Guru Pathik’s risky shortcut.
• Aang decided to return to Guru Pathik and continue his training after thanking Kahn.
• Aang asked whether Kahn had opened all his chakras, and Kahn said he was still far from doing so.
