A friend asked me to answer this question: What is the name of the person who is reminded of Kaecilius by Strange's arrogance and ambition?, using the article: In Kathmandu, the sorcerer Kaecilius and his zealots enter the secret compound Kamar-Taj and behead its librarian. They steal a few pages from an ancient, mystical text belonging to the Ancient One, a long-lived sorcerer who has taught every student at Kamar-Taj, including Kaecilius, in the mystic arts. The Ancient One pursues the traitors, but Kaecilius and his followers escape. In New York City, Stephen Strange, a wealthy, acclaimed, and arrogant neurosurgeon, severely injures his hands in a car accident, leaving him unable to operate. Fellow surgeon and former lover Christine Palmer tries to help him move on, but Strange vainly pursues experimental surgeries to heal his hands, nearly bankrupting himself. Strange learns about Jonathan Pangborn, a paraplegic who mysteriously regained use of his legs. Pangborn directs Strange to Kamar-Taj, where he is taken in by Mordo, a sorcerer under the Ancient One. The Ancient One demonstrates her power to Strange, revealing the astral plane and other dimensions such as the Mirror Dimension. She reluctantly agrees to train Strange, whose arrogance and ambition remind her of Kaecilius. Strange studies under the Ancient One and Mordo, and from ancient books in the library that is now guarded by Master Wong. Strange learns that Earth is protected from threats from other dimensions by a shield generated from three buildings called Sanctums, in New York City, London, and Hong Kong, which are all connected and accessible from Kamar-Taj. The sorcerers' task is to protect the Sanctums, though Pangborn instead chose to channel mystical energy only into walking again. Strange progresses quickly, and secretly reads the text from which Kaecilius stole pages, learning to bend time with the mystical Eye of Agamotto. Mordo and Wong warn Strange against breaking the laws of nature, drawing a comparison to Kaecilius' desire for eternal life., what would be the answer ?
The answer to this question is:
Ancient One
