Beings of Exclamation

Great Caesar's Ghost is the spirit of a departed leader the the Eternal City (the name was a misnomer, it turned out). Once tried to build a tower into High Heaven, saw something while at the very top, stuff went down, and is now a ghost.

You know when you see something that leaves you speechless and you whistle in astonishment? The Whistler did that when it saw the birth of the world. Technically qualifying as a wind god, the Whistler has mastery over wind instruments such as flutes, fifes, and whistles of all sorts. And cleanliness, some believe. It is commonly agreed that the Whistler whistling in astonishment on the seventh day of Kingdom Come will officially signal the end of the world.
