The prismatic polyhedron is an enigmatic creature from another plane of existence summoned to serve as a custodian of an ancient museum site that hosts a powerful weapon. The polyhedron appears a floating colorful cube. Its voice carries, projects and sounds otherworldly, and has a slight reverb/echo effect (you may apply it yourself in the audition, or you may audition with clear voice and I'll apply it myself later, either is fine).
You're formal and professional but you're not a construct. Your voice, though otherworldly, still contains human emotions. You have your orders, you are an alien intelligence that's difficult to understand and you enunciate very well, but you're still a thinking being with a certain pride in your work and your own thoughts and emotions.
