Final answer:
The provided texts do not specify the city Victor leaves to exact his revenge. Without additional context or a specific literary source, an accurate answer cannot be given.
Step-by-step explanation:
The excerpt provided does not clearly specify which city Victor leaves to exact his revenge, as the texts provided are from different contexts and do not appear to be directly related to a character named Victor seeking revenge.
However, there are mentions of a heartbroken King who leaves the city in self-imposed exile, which could be a general reference to a common theme in literature where a character seeks revenge after experiencing a significant loss or betrayal.
Yet without a more specific literary reference, such as a book title or author, it is not possible to provide an accurate response to the question, "What city does Victor leave to exact his revenge?". Furthermore, the mention of Victor Arnautoff and his artwork does not pertain to a narrative about a character named Victor, but rather to the artist and his murals in San Francisco.
