The Battle at the Hong Kong Sanctum was a battle that pitted the Masters of the Mystic Arts against Kaecilius and his Zealots.

Having attacked the London and New York sanctums and killed the Ancient One, Kaecilius initiated the final phase of his plan to merge Earth with the Dark Dimension.

His efforts were thwarted when Doctor Strange used the Eye of Agamotto to reverse time and prevent the final sanctum from being destroyed.
