Battle at the Hong Kong Sanctum

The Battle at the Hong Kong Sanctum was an attack on the Hong Kong Sanctum orchestrated by the Zealots as a final stage in the initiation of bringing Dormammu to Earth.

Background
Doctor Strange was trained by the Masters of the Mystic Arts following a car accident that ruined his hands. After spending all his money on a possible cure, he was instructed by Jonathan Pangborn to go to Kamar-Taj in Kathmandu, Nepal. He became a protégé of the Ancient One and learned of various spells and relics from Karl Mordo and Wong, including the Eye of Agamotto.

Kaecilius and the Zealots, following the Theft of the Book of Caligostro recited a ritual to summon power from the Dark Dimension. They attacked both the London Sanctum and the New York Sanctum and wounded the Ancient One during a battle in the Mirror Dimension. She would later die in the Metro-General Hospital, while the Zealots escaped to Hong Kong to destroy the final Sanctum.

Battle
TBA

Aftermath
Doctor Strange confronted Dormammu in the Dark Dimension and annoyed him enough via time loop to leave Earth with Kaecilius and the remaining Zealots. Strange becomes the Master of the Sanctum Sanctorum.

Karl Mordo departs from the Masters of the Mystic Arts after Strange disregarded the consequences for tampering with time to defeat Dormammu. He would later go on a personal vendetta to cleanse the world of sorcerers, starting with Jonathan Pangborn.
