|Title:||Golden Theater Swing / Golden Theater of the Deranged (English Version)|
"Behold my glory... Hear the thunderous applause... Sit down and praise... My Golden Theater! Kingdom of Heaven and Hell... My heaven, reconstructed! This is where the limelight shines!"
Aestus Domus Aurea: Golden Theater Swing (招き蕩う黄金劇場, ?) is the Domus Aurea, the theater designed by Nero and constructed in Rome during her lifetime, given form and reproduced through prana with a method extremely similar to that used by Reality Marbles. Rather than being a materialization of her inner world, it is High-Thamaturgy that only Nero, 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 Sol", can perform. It is an "absolute imperial zone" which allows the owner to achieve their aspirations.
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 they are made progressively weaker over time.
