This minor audience chamber is designed as a personal viewing hall. Aside from the obvious weaponry strewn throughout, and the whimsically impossible imaginary precautions, motion limiters, force fields, air transfer devices, and psionic dampers, it is also designed to be assassination proof. Even the architecture helps with this.
Take note of the steps leading up to the dias. All unevenly spaced to prevent a good run up to the throne. This is a brutal audience hall. Just because it was intended to be assassination proof,doesn’t mean no one has made the attempt. Nor does it mean that every attempt has failed.
