Aestus Domus Aurea

is the , the theater designed by Nero Claudius and constructed in Rome during her lifetime, given form and reproduced through magical energy with a method extremely similar to that used by Reality Marbles. It is different from a Reality Marble, which covered the current World with a different World. The Golden Theater could persist for long periods because it was built on top of the current World. Rather than being a materialization of her inner world, it is greater magecraft that only Nero can perform, who believes without a doubt that before her status as an emperor, she is "an artist who rivals Apollo" and "a chariot driver that rivals ". It is an "Absolute Imperial Zone" which allows the owner to achieve their aspirations.
This Noble Phantasm represents the explosion of her bothersome artistic talent. Its precise name was Aestus Estus Domus Aurea. In Latin, Aestus Estus meant "passion" and "heat", while Domus Aurea was the name of the theater that was constructed. It is a theater based on the palace Nero had built after her original one was burned to the ground. It was also a grand villa built upon the ruins of the homes of the aristocracy that once covered the famed . It was the manifestation of the tale of Nero declaring "Heed my song!" and locking everyone in the theater to listen to her singing.
It created a Golden Theater in which everything was advantageous to Nero, and made it into a battlefield. While deployed, enemies trapped are weakened and buildings can be customized by changing its shapes and functions. Putting it simply, she can ignore the building process and project the buildings instead, in which she can then invoke her own rules. When the Golden Theater activates, Nero's sword would be shrouded in flames like that of , causing an inferno, and rose petals would dance in the air. It seemed that there was the Silver Workshop for Saber's artistic endeavors, and the "Blazing Kitchen" for cooking competitions. Such was the will of Her Majesty.

When the theater was first opened for business, many of the spectators left midway through the performance, causing an outraged Nero to blockade all doorways once the second performance began and not let even one person leave until the curtains of the stage were down. As a result, escape - without Nero's permission or cessation of the Phantasm - is virtually impossible.
In the game, the ability causes Saber's attacks to ignore the opponent's defense, and the opponents are made progressively weaker over time.
