Arc 14The Sanctum War
The Young Avengers confronted Vulture, while Xia Yu learned why the Ancient One had been told to kill Doctor Strange and helped strengthen Earth’s Sanctums. Kaecilius destroyed several Sanctums and cornered Strange, Wong, and Mordo at the Sky Temple until Xia Yu arrived.
- Spider-Man, Harry, and Tate fought Vulture aboard a Hudson River cruise boat, saved the passengers from the splitting ship, and were approved as the Young Avengers under Tony’s conditions.
- Tony and Xia Yu left Vulture’s fate to Spider-Man, who accepted a three-year house-arrest arrangement in AC City, and Vulture told his family the truth, and Peter apologized to him.
- The Ancient One showed Xia Yu a hidden Sanctum and revealed that its altar had instructed her to kill Doctor Strange, but the altar’s strange courtyard led Xia Yu to an old man who recognized him as a transmigrator.
- The old man explained that Xia Yu should wait for Ragnarok before absorbing Asgard’s origin, returned the system’s orb to him, and directed him to help the Ancient One build a new Sanctum in Sky City.
- Xia Yu and the Ancient One established the Sky Temple beside the Avengers Compound and strengthened its protective formation, while Tate challenged Doctor Strange and impressed him with his flying swords.
- Dormammu empowered Kaecilius, who destroyed the London and New York Sanctums before attacking the Sky Temple, where Strange, Wong, and Mordo fought him as the Ancient One remained missing.
- A magical cloak chose Doctor Strange as its master, but Kaecilius overpowered the sorcerers and transformed into a monstrous form, and Xia Yu appeared at the Sky Temple and challenged him.
