What is that sound bursting in the sky? Is it the trumpet of some archangel? Or is it just a prank by some aeronaut? No! None of that!

It is a strange, unprecedented phenomenon that no one can explain. Today it can be heard over America, but tomorrow it might be heard over Europe, or over Asia, or who knows? Perhaps you heard it too in your home.

Thousands of telescopes, binoculars, and spyglasses are vigilantly monitoring the sky, various bizarre opinions are voiced, people are staying awake, curious and fearful, but the answer is one, and the only one who can provide it is Robyros the Conqueror!
